Nothing is wrong with that, I just (blush) didn't think to try == instead of
"is".
Since == works, that also means that using a method as a key to a dictionary
also works reliably:
>>> d = {c.f: 'special case 1'}
>>> d[c.f]
'special case 1'
So I have no more complaints, other than I expected "is" to work and it
didn't...but I can do what I want and it isn't awkward, so I'll just go
back in my hole now...
Thanks,
David H.
