[Python-ideas] Infix application of binary functions

Thought about it some more. Here’s a more general formula:

class InfixArity(object):
    def __init__(self, arity):
        self.arity = arity
        self.args = []

    def __call__(self, func):
        self.func = func
        return self

    def __add__(self, arg):
        if len(self.args) < self.arity:
            return self
            return self.func(*self.args)

    __radd__ = __add__

Infix = lambda func: InfixArity(2)(func)

And of course, one can use __mul__ or __div__ or whatever to taste. "1
// add // 2” doesn’t make me instantly vomit in my mouth. ;-)
