That's a complicated story. I'll be happy to explain it over a beer at IPC10 (if we both make it there ;P) but the short version is that XS4ALL is not an ordinary company, we use a lot of opensource software, and my boss suggested it. The traffic is peanuts, by the way, I think the more costly part is the rackspace in our system room. > I think that Skip's proposal would go a long way (sketching here > a bit): > It should be possible for the compiler to detect an if-elif-else > construct which has the following signature: > if x == 'first':... > elif x == 'second':... > else:...

I don't think this will have as much impact as you think. But testing it like Martin suggested would be a good idea, and the compiler/interpreter is a fun thing to play and experiment with.

I don't like needing the break (hence my comments about fallthrough) and I think the switch, case and else should all be indented to the same level, just like 'if/elif/else'. > def whatis(x): > switch x: > case 'one': > print '1' > break > Turns out that this look very Pythonic :-) I like my version better, with the exception of the parentheses around 'x' in 'switch(x):' :) > Sure smells like PEP-time :-) Aye, but lets do it while Guido is still on paternity leave so we at least get to finish the proposal before it's -1'ed :) -- Thomas Wouters <thomas@xs4all.net> Hi!
