Previously, file used global variables extensively and did not 'use strict'

where appropriate and the file now runs fully under strictures. Other
than that, no attempt was made to improve the design of the file or the

Make set-magic handle vstrings properly
Assigning a vstring to a tied variable would result in a plain string
in $_[1] in STORE.
Assigning a vstring to a magic deferred element would result in a
plain string in the aggregate’s actual element.
When magic is invoked, the magic flags are temporarily turned off on
the sv so that recursive calls to magic don’t happen. This makes it
easier to implement functions like Perl_magic_set to read the value of
the sv without triggering get-magic.
Since vstrings are only considered vstrings when they are SvRMAGICAL,
this meant that set-magic would turn vstrings temporarily into plain
strings. Subsequent copying (e.g., in STORE) would then fail to copy
the vstring magic.
This commit changes mg_set to leave the rmagical flag on, since it
does not affect the functionaiity of set-magic.

[perl #118839] Make ‘n’ debugger cmd respect lv subs
The ‘n’ debugger command, which is supposed to step over subs, was not
stepping over lvalue subs.
This is a regression from 5.8, but 5.8 was worse.
This bug did not occur in 5.8 because there was no mechanism back then
for handling lvalue subs specially (via DB::lsub), so assignment to an
lvalue sub was completely broken under the debugger.
Perl 5.10 introduced DB::lsub. The implementation in perl5db.pl
contains these lines at the end of the sub:
# Pop the single-step value back off the stack.
$single |= $stack[ $stack_depth-- ];
# call the original lvalue sub.
&$sub;
The regular DB::sub does this:
{
no strict 'refs';
@ret = &$sub;
}
# Pop the single-step value back off the stack.
$single |= $stack[ $stack_depth-- ];
Notice how $single (i.e., $DB::single) is modified before and after
the sub call, respectively. The order is different.
There are two types of lvalue list context for lvalue subs. (foo)=3
will allow sub foo:lvalue{@a} to return the array itself. \(foo) and
bar(foo) will flatten the array.
So there is no way in pure Perl to capture the return value and have
it returned to the caller unchanged. That is why DB::lsub has to call
the sub last of all (and have the context propagated).
The solution here is to use localisation to accomplish the assigment
to $single after the lvalue sub exits.

Allow => to quote built-in keywords across lines
If I have a sub I can use its name as a bareword as long as I suffix
it with =>, even if the => is on the next line:
$ ./perl -Ilib -e 'sub tim; warn tim' -e '=>'
tim at -e line 1.
If I want to use a built-in keyword’s name as a bareword, I can put =>
after it:
$ ./perl -Ilib -e 'warn time =>'
time at -e line 1.
But if I combine the two (keyword + newline), it does not work:
$ ./perl -Ilib -e 'warn time' -e ' =>'
1373611283 at -e line 1.
unless I override the keyword:
$ ./perl -Ilib -Msubs=time -e 'warn time' -e ' =>'
time at -e line 1.
=> after a bareword is checked for in two places in toke.c. The first
comes before a comment saying ‘NO SKIPSPACE BEFORE HERE!’; it only
skips spaces and finds a => on the same line. The second comes later;
it skips vertical space and comments, too.
But the second check is in a code path that is not reached by keywords
that are not overridden (as is the ‘NO SKIPSPACE’ comment).
This commit adds an extra check for built-in keywords after we have
determined that the keyword is not overridden. In that case, there is
no reason we cannot use skipspace, as we no longer have to worry about
what PL_oldbufptr etc. point to.
This commit leaves __DATA__ and __END__ alone, since they
are special, problematic and controversial. (See, e.g.,
<https://rt.perl.org/rt3/Ticket/Display.html?id=78348#txn-1234355>.)

t/base/lex.t: Test pyoq with comment before delim
perlop says:
There can be whitespace between the operator and the quoting
characters, except when C<#> is being used as the quoting character.
C<q#foo#> is parsed as the string C<foo>, while C<q #foo#> is the
operator C<q> followed by a comment. Its argument will be taken
from the next line.
But I do not find tests for this anywhere. Here are some.

Add a const qualifier for the arg to the S_CvGV inline function in cv.h.
In addition to correctly describing the behavior of S_CvGV, this avoids
warnings in op.c:Perl_report_redefined_cv, where the old (CV *) cast
removed the 'const' qualifier. Observed on OpenBSD 5.2 with gcc-4.2.1.

With PERL_GLOBAL_STRUCT_PRIVATE "global" variables are in a structure in

7a834142adbc51cc (Aug 2003), which added code and

did not add a perl.valgrind target, despite adding dependencies on it. Hence
the various targets which depended on it could never have worked. Of the
4 similar targets, only test.valgrind works because unlike the other 3,
it depends on test_prep, not test_prep.valgrind

[perl #118627] Don’t do COW when creating ${"_<-e"}[0]
The lexer does not expect PL_linestr (an SV holding the current line
of Perl code being parsed) to do copy-on-write. It expects to be able
to manipulate that SV to its hearts content with impunity. The one
piece of code that can cause it to do that is S_update_debugger_info,
when called with a SV for the first argument. The only time it is
called that way is for line 0 of the main script, containing state-
ments generated from command line arguments (e.g., ‘use strict’ from
‘-Mstrict’), and it is called with PL_linestr as its argument.
If ${"_<-e"}[0] ends up sharing the buffer with PL_linestr, bad things
will happen, as the lexer is going to continue to modify that buffer.
Usually we get this:
$ ./perl -It/lib -d:switchd_empty -e'print @{"_<-e"}' |less
^@se Devel::switchd_empty;
print @{"_<-e"}
So force S_update_debugger_info to do a non-COW copy.

Split the handling for "Illegal character" and "Illegal character after '_'"
After applying this patch, both can now be triggered at once, whereas
previously any use of '_' would trigger the "after '_'" variant. Since
the two warnings warn for different reasons, there's no reason to
conflate the two. Also updated perldiag with a clearer explanation
of the tighter restrictions after an underscore.
(In the tests, the change of uniproto12 to uniproto13 is merely correcting
an error from a previous patch, reusing the name would conflate
two kinds of tests in one statement).
