Hey, thanks for piping up, Bob!  If you've got an implementation of
this, you must be the same Bob who sat on the couch at PyCon and coded
this stuff up while Donovan Preston and I were designing the
syntax... you sure were a Python-coding machine!  A pleasure to meet
you; I never caught your last name.  I guess if you still have an
implementation, it's still working out for you... (?)
