My last comment sounded more glib than intended.  Since I've already 
used MethodStack in my own code, I think it can be generally useful in 
cleaning up repetitive alias_method calls.

I might try submitting it to facets, with two changes: change names to 
push_instance_method/pop_instance_method for symmetry with 
Module#instance_method, and add 1.8.6 compatibility.
