Functions to create class methods chain-friendly (as in A.b().c().d()) and a function to create function chains (as in: make_consuming_chain(a, b, c)() #=> c(b(a())) )

def make_consuming_chain(*functions, **kwargs):
    '''
    Return a function that will call functions in sequence, passing the return down the chain of functions
    '''
    return reduce(lambda acc, f: lambda *args, **kwargs: f(acc(*args, **kwargs)), functions)

def make_chainable(method):
    '''
    Make a method returning none return self
    '''
    return lambda self, *args, **kwargs: method(self, *args, **kwargs) or self
