I prefer to remain pseudonymous, and I don't have commit access.
Yeah... they're not terribly useful - more or less there for the sake of
being there. Batteries included and all that
...but now I've got a more useful idea for a function wrapper around
predicate functions to make them a little more functionally inclined.
def hasnext(x): return hasattr(x, "next")
def hasiter(x): return hasattr(x, "__iter__")
isiterable = hasnext or hasiter #or/and/not operators construct new
isEmptyIterable = isiterable and not predicate(bool)
isgenerator = isiterable and (lambda x: hasattr(x, "send") and hasattr(x,
filter(isgenerator or callable, SomeSequence)
