How would that be any improvement over this? . x = foo(x) where: . x = math.pi/4.0 . def foo(x): print 'just for illustration', x Can anyone think of a use case for embedding "where" inside an expression as opposed to making it part of a simple statement? And, if so, is the benefit of it worth the massive hit in readability. > or is this legal? > > for y in ([foo(x) for x in bar] where: > bar = xrange(5) > ): baz(y) where: > def baz(arg): return arg*2 Here, I can only hope not. One reason I proposed a where...do syntax is so that, if you wanted to localize a variable to a for loop or some other compound statement, you could do it with a minimum of fuss. . where: . bar = xrange(5) . def baz(arg): return arg*2 . do: . for y in [foo(x) for x in bar]: . baz(y) > Not trying to sabotage the idea, really, just looking for clarification ;-) That's ok. For it fly, it's got to be able to withstand the flak. -- CARL BANKS -- http://mail.python.org/mailman/listinfo/python-list
