I would spell the above like this:
def timeConsumingCalculation():
pass
def useit(it):
pass
def aif(first,second):
res = first()
if res:
second(res)
aif(timeConsumingCalculation,useit)
Sure, it requires me to define function useit instead of embedding the
code in aif call, but that has never been a problem for me: in reality,
the code I would want to execute would be complex enough to warrant it's
own function anyway. Of course, YMMV.
