Subject: eval '__PACKAGE__' in debug mode do not return right package
From: kes-kes@yandex.ru
This is a bug report for perl from kes-kes@yandex.ru,
generated with the help of perlbug 1.40 running under perl 5.24.0.
-----------------------------------------------------------------
[Please describe your issue here]
[DOC](https://perldoc.perl.org/functions/eval.html)
>An eval '' executed within a subroutine defined in the DB package doesn't
see the usual surrounding lexical scope, but rather the scope of the first
non-DB piece of code that called it
How to reproduce:
$ cat Devel/DB.pm
package DB;
sub DB {
print eval '__PACKAGE__';
}
1;
$ cat t.pl
print __PACKAGE__;
$ perl -d:DB t.pl
DBmain
Expected:
mainmain
[Please do not change anything below this line]
