Perhaps I should reiterate: ;) Oh, and ;)
The CPython source code is filled with gotos -- with a rough grep count,
I found over 2000. And, while I wouldn't care to inspect them all, I'd
guess that they're mostly quite appropriate. A lot of them look like
"goto fail", "goto finally", etc. and are used to handle error
conditions. Heck, the patch I wrote to add key= arguments to min() and
max() in Python 2.5 uses goto for exactly this purpose.
That said, I don't think my joke was really that inaccurate -- I have
yet to see a good use case for gotos in Python. Why use gotos when you
have an efficient exception handling mechanism?
