I would expect it to work that way because both UnboundMethods are 
pointing at the same exact method. Perhaps I am expecting too much, 
since I don't know how it works internally. But, from the outside, I 
expected it to essentially make another reference to that method's 
object and pass it back.

I'm guessing (from your reaction) that what actually happens behind the 
scenes when you retrieve an UnboundMethod that way is entirely 
different from what I had assumed? If, in retrieving the UnboundMethod 
object, it creates a new wrapper object, and passes that back, it would 
make perfect sense that the hashes and ids wouldn't match. Even so, I 
wish they would match :)

Of course, I'm only inferring, so I could easily be way way out in left 
field here.
