Subject: | author should take array to match META.yml spec and Module::Build |
The META.yml spec supports multiple authors via an array:
http://module-build.sourceforge.net/META-spec-blead.html#author
Module::Build does as well.
So in Metadata.pm, the handling of 'author' should be updated to take a single value or an array of authors. Other places in the code that rely on this data may need updated as well.
