Hacking Infix Operators into Python with Decorators

Yup. I think it is the alternative definition of a "hack". :)

Python has builtin alternate forms of all infix operators in the "operator" module:

    from operator import add
    add(x, y)

Like in your example, you can't simply give it more args (since infix operators are binary operators and may not be associative). But you could combine it with some other builtins like so:

    from operator import add
    reduce(add, [x, y, z])

Of course, for the specific case of addition, you can simply use the builtin "sum()" function, which is almost equivalent to above (sum() assumes an initial value of 0 by default, so sum(list) === reduce(add, list, 0))

The difference being that this would never fly in a python codebase.
