Better RPM Perl Auto-Requires

Brain dump. Comments welcome and appreciated, on the talk page.

Needed

1. Understands "use base", "use parent", etc, constructs.
2. Understands Moose
   1. "extends" - subclassing
   2. "with" - roles
   3. "metaclass" - metaclasses
   4. "traits" - metaclass roles
3. Understands Catalyst plugin speficication syntax
   • This should be extensible to other module classes
4. Doesn't generate duplicates. e.g.: perl(Foo) and perl(Foo) >= 1.9
5. Better able to deal with the wonders of Perl versioning; e.g.
   • 1.20a stays 1.20a
   • 1.20 becomes 1.020000 (version triplet)

Questions

1. Should we attempt to compile? (a la perl -wc or Module::ScanDeps)
   • PROS: highly accurate
   • CONS: may fail for a variety of reasons
2. Should we try to normalize the versions?

use base constructs correctly evaluated	use base 'XXX';	perl(base)	perl(base) perl(XXX)		Need also to correctly evaluate use parent ..., etc.
No duplicate provides					We often see duplicate requires. These are harmless, except in the case where one requires is versioned and another unversioned. This might need to be addressed at a higher level than perl.prov.
Mo*se subclassing	extends 'Some::Class';		perl(Some::Class)		Multiple classes can be specified; not possible to specify version with this syntax.
Mo*se roles	with 'Some::Class'; # multiple roles at once with 'Role::A', 'Role::B';		perl(Some::Class) perl(Role::A) perl(Role::B)		Multiple classes can be specified; not possible to specify version with this syntax.
Mo*se traits	...in an attribute specification: ... traits => [ 'X', 'Y' ]		perl(Moose::Meta::Custom::Trait::X) perl(Moose::Meta::Custom::Trait::Y)		This is going to be tricky.
Mo*se metaclasses
Catalyst and other plugin syntax	use Catalyst qw/ -Debug ConfigLoader Static::Simple/;	perl(Catalyst)	perl(Catalyst) perl(Catalyst::Plugin::ConfigLoader) perl(Catalyst::Plugin::Static::Simple)		Note that it is quite common for a Catalyst app to have a multi-line "use Catalyst" statement; we need to be able to deal with multi-line
Ability to include/exclude
