  [BUG FIXES]

  - The definition context (package, file, & line) for attributes on
    Class::MOP and Moose metaclasses was wrong in all cases.

  - Slight tweaks to the syntax used for hashes in a few tests, that were
    broken by a recent Test::More release that started using a new namespace
    that clashes with a (bareword) type name in these tests. (PR#141,
    D.Maestro)
