If you feel about it that way, I recommend that you let it mature a
bit more.

If you really like this so much, please realize that you can do this
for *any* instance method.  The identity

   C.foo(C()) == C().foo()

holds for all "regular" methods.  (Since 2.2 it also holds for
extension types.)  If we were to do this, we'd be back at square two,
which we rejected: list instances having both a sort() and a sorted()
method (square one being no sorted() method at all :-).
