| Subject: | ReportVersions fails when modules have conflicting symbols |
Marked as critical because the plugin cannot be used at all when two or
more modules conflict.
The ReportVersions plugin seems to be importing symbols from all modules
into one package. Mayhem ensues when two or more modules export
conflicting symbols.

The above fails in exactly the same way as using conflicting modules:
% perl -wle 'use Moose; use MooseX::Role::Parameterized'
