I don't like the idea of turning words into operators. I'd much rather
see something like:

@infix('..')
def interval(x, y):
    return range(x, y + 1)

assert 5 .. 9 == interval(5, 10)

This would also allow us to start working on doing away with the magic
method names for current operators, which I think would be an
improvement.

As others have pointed out, you do need to do something about operator
precedence. For existing operators, that's easy - they keep their
precedence. For new operators, it's harder.

You also need to worry about binding order. At the very least, you
can specify that all new operators bind left to right. But that might
not be what you want.
