Subject: bug in install from cpanm (Contextual-Return-0.004007)

Hi, I have a bug when I try to install Statistics-PCA, I have an error from Contectual::return in the method to get the version. I report the bug to you because I think the way to check version in the Contectual::return package has changed, so that is why the install of Statistics-PCA failed.

Thanks for the report, Rémy. I can't find the problem within Contextual::Return. It definitely specifies a $VERSION variable (on line 90). Perhaps the bug is in cpanminus and you should report it to Miyagawa??? Damian

See https://rt.cpan.org/Ticket/Display.html?id=94940 "It seems M::M is confused by the "package DB" on line 13 of C::R. If you ask the version of the "DB" package it is correct." Test case: % perl -MModule::Metadata -le'print (Module::Metadata->new_from_module("Contextual::Return", inc => \@INC)->version' currently gives no output.

Thanks for the update, Tom. Looks like this is definitely a problem in the toolchain, as the "package DB" trick is a Perl introspection technique of longstanding. Damian

This cannot be fixed in Module::Metadata without breaking other things -- we simply cannot tell that the scope of the "package DB" statement has ended and the $VERSION declaration is back in the Contextual::Return namespace without doing a full parse of the file (e.g. via PPI), which requires far more overhead than can be afforded. In order for the $VERSION to be detected statically, it must be assigned before the next 'package' directive. Attached is a patch (there was no git repository listed in the distribution's metadata).
