Bug #100724 for Moose: Moose::Exporter synopsis just doesn't work

I've tried using Moose::Exporter to add some syntactic sugar, but the documentation does not help. Adapting examples from the SYNOPSIS, eliminating the obvious missing examples: Show quoted text

> package MyApp::Moose; > > use Moose (); > use Moose::Exporter; > > Moose::Exporter->setup_import_methods( > with_meta => [ 'has_rw' ], > also => 'Moose', > ); > > sub has_rw { > my ( $meta, $name, %options ) = @_; > $meta->add_attribute( > $name, > is => 'rw', > %options, > ); > } > > 1;

and Show quoted text

> package MyApp::User; > > use MyApp::Moose; > > has 'name'; > has_rw 'size'; > thing; > > no MyApp::Moose; > > 1;

Then running (on Perl 5.20.1): perl -I lib/ -MMyApp::User gives me the error: Show quoted text

> Bareword "thing" not allowed while "strict subs" in use at > lib/MyApp/User.pm line 7. > Compilation failed in require. > BEGIN failed--compilation aborted.

The "thing;" sub call is supposed to go with the import of \&Some::Random::thing, which you removed from the original example, so there's no error here. I do see a different error in the synopsis, introduced when we extended the syntax to accept bare subrefs, so thanks for bringing this up.

Removing the call for the "thing" sub, and we still get the error: Show quoted text

"has_rw 'size'" (Do you need to predeclare has_rw?) syntax error at lib/MyApp/User.pm line 7, near "has_rw 'size'" BEGIN not safe after errors--compilation aborted at lib/MyApp/User.pm line 10.

Sorry, I can't reproduce. You'll have to paste the (full) code you're using.
