Well more of a suggestion than a bug

[byterock]

I added in 'no_extra_attributes'
here
https://github.com/byterock/Test-Moose-More/blob/master/lib/Test/Moose/More.pm

and I have found this to be very useful in my automated testing as it points out extra stuff in my code base that

1. should not be there or
2. need to update a test or
3. build a new test.

Will most likely add in 'no_extra' at the class level so it does the same across a class for me

Nice.

This sounds something like a "strict mode" for validate_*, namely "if you find extra stuff, fail"; something I've been thinking about for a while now. Hm.
