I'm just relaying the contents of: https://github.com/Perl/perl5/pull/10/files Because I would be loath if 5.23.3 and 5.24.1 shipped without at least ensuring this properly considered. The essential issue is that by localising @INC in base.pm, any changes made to @INC by the module being loaded are lost. And so instead of assuming @INC can be simply reverted to its previous state, it uses a scope guard, and thus tries to effectively localise *only* the absense of '.' by: a) only adding cleanup logic if $INC[-1] is in fact '.' b) reinserting '.' in the cleanup block on base->import scope exit. Presently, localising is done regardless of the presence of a ".", making any @INC modification in base.pm impossible, even if the user had already removed '.' themselves. There is other feedback on https://github.com/Perl/perl5/pull/10 potentially worth considering. Though the contents of the patch are submitted here verbatim as an attachment for P5P's convenience. -- Kent KENTNL - https://metacpan.org/author/KENTNLThread Next
