Subject: isa => 'SomeClass', handles => qr// dies if SomeClass isn't loaded
If you have an attribute with "isa => 'SomeClass', handles => qr/\w_class/, you get a backtrace like the following if SomeClass isn't loaded: Couldn't load class (VCI::Abstract::Project) because: VCI::Abstract::Project already has a metaclass, but it does not inherit Moose::Meta::Class (Class::MOP::Class=HASH(0x36b13b0)). at /usr/lib64/perl5/vendor_perl/5.10.0/x86_64-linux-thread-multi/Moose.pm line 166 Moose::init_meta('Moose', 'for_class', 'VCI::Abstract::Project', 'metaclass', undef) called at /usr/lib64/perl5/vendor_perl/5.10.0/x86_64-linux-thread- multi/Moose/Exporter.pm line 354 Moose::Exporter::__ANON__('Moose') called at lib/VCI/Abstract/Project.pm line 2 VCI::Abstract::Project::BEGIN() called at lib/VCI/Abstract/Project.pm line 2 eval {...} called at lib/VCI/Abstract/Project.pm line 2 require VCI/Abstract/Project.pm called at /usr/lib64/perl5/vendor_perl/5.10.0/x86_64-linux-thread- multi/Class/MOP.pm line 114 Class::MOP::__ANON__() called at /usr/lib/perl5/vendor_perl/5.10.0/Try/Tiny.pm line 71 eval {...} called at /usr/lib/perl5/vendor_perl/5.10.0/Try/Tiny.pm line 67 Try::Tiny::try('CODE(0x300c308)', 'Try::Tiny::Catch=REF(0x399eb60)') called at /usr/lib64/perl5/vendor_perl/5.10.0/x86_64-linux-thread- multi/Class/MOP.pm line 125 Class::MOP::load_first_existing_class('VCI::Abstract::Project') called at /usr/lib64/perl5/vendor_perl/5.10.0/x86_64-linux-thread- multi/Class/MOP.pm line 137 Class::MOP::load_class('VCI::Abstract::Project', undef) called at /usr/lib64/perl5/vendor_perl/5.10.0/x86_64-linux-thread- multi/Moose/Meta/Class.pm line 288 Moose::Meta::Class::superclasses(undef, 'VCI::Abstract::Project') called at /usr/lib64/perl5/vendor_perl/5.10.0/x86_64-linux-thread-multi/Moose.pm line 53 Moose::extends('Moose::Meta::Class=HASH(0x3019b90)', 'VCI::Abstract::Project') called at /usr/lib64/perl5/vendor_perl/5.10.0/x86_64-linux-thread- multi/Moose/Exporter.pm line 293 Moose::extends('VCI::Abstract::Project') called at lib/VCI/VCS/Bzr/Project.pm line 9 require VCI/VCS/Bzr/Project.pm called at lib/VCI/VCS/Bzr/Repository.pm line 5 VCI::VCS::Bzr::Repository::BEGIN() called at lib/VCI/Abstract/Project.pm line 2 eval {...} called at lib/VCI/Abstract/Project.pm line 2 require VCI/VCS/Bzr/Repository.pm called at - line 0 main::BEGIN() called at lib/VCI/Abstract/Project.pm line 2 eval {...} called at lib/VCI/Abstract/Project.pm line 2 BEGIN failed--compilation aborted at lib/VCI/Abstract/Project.pm line 2.

Your error message doesn't match your description, and I cannot reproduce this. based on your description. Can you write a test that shows the bad behavior?

The backtrace he pasted is what happens later, when SomeClass is loaded somewhere else, and tries to 'use Moose'.
