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.
