overwrite the glob. The original glob, however, is
immutable.
-Many Perl operators did not distinguish between these two types of globs.
+Some Perl operators did not distinguish between these two types of globs.
This would result in strange behaviour in edge cases: C<untie $scalar>
-would do nothing if the last thing assigned to the scalar was a glob

(because it treated it as C<untie *$scalar>, which unties a handle).
Assignment to a glob slot (e.g., C<*$glob = \@some_array>) would simply
assign C<\@some_array> to C<$glob>.
