+=head2 Subroutines in the CORE namespace
+
+Many Perl keywords are now available as subroutines in the CORE namespace.
+These cannot be called through references or via C<&foo> syntax yet, but
+must be called as barewords. In other words, you can now do this:
+
+ BEGIN { *entangle = \&CORE::tie }
+ entangle $variable, $package, @args;
+
+This currently works for overridable keywords other than C<not>, C<dump>,
+C<getprotobynumber> and the infix operators.
+
+Work is under way to allow these subroutines to be called through
+references.

=head2 C<__FILE__()> Syntax
The C<__FILE__>, C<__LINE__> and C<__PACKAGE__> tokens can now be written
=item *
-XXX L<message|perldiag/"message">
+L<&CORE::%s cannot be called directly|perldiag/"&CORE::%s cannot be called directly">
+
+(F) You tried to call a subroutine in the C<CORE::> namespace
+with C<&foo> syntax or through a reference. The subroutines
+in this package cannot yet be called that way, but must be
+called as barewords. Something like this will work:
+
+ BEGIN { *shove = \&CORE::push; }
+ shove @array, 1,2,3; # pushes on to @array
