Re: Moose::Meta::Role::rename_attribute

Chris,

What would be the use case for this?

Also note that it is an expensive operation since it removes all the  
methods and other items associated with the attribute. A simple alias  
(*foo = \&bar) or delegate method (sub foo { shift->bar }) would be  
much more efficient and handling most of the use cases that I can  
think of.
