Not on functions, but on classes/instances. So something like this might
work for you (untested):
class FunctionComposer(object):
def __init__(self, f=None):
if f is None:
f = lambda x: x
self._f = f
def __call__(self, *args, **kwargs):
return self._f(*args, **kwargs)
def __mul__(self, other):
def combined(*args, **kwargs):
return other(self._f(*args, **kwargs))
return FunctionComposer(combined)
fc = FunctionComposer
Then you can write
(fc() * list * reversed * sorted)(items)
