If you are calling ->does on an attribute object a lot, it ends up calling 
resolve_metaclass_alias a lot. t0m on IRC noticed this and added some 
caching that speeds this up by a huge degree.

This will be in the Moose 0.60 release, which I expect to do some time 
today.

In a future release, we may also add caching to $attr->does() when a class 
is made immutable.
