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
