There won't be unless you rule out using "x > y" as an expression that
gives the default value. But doing that will make Python's grammar way
too complicated, and you're still left with the problem of "x, y = a <
b, b > c" which is legal today.

It's my understanding that Ruby has run into a lot of ambiguity with
its use of | as both a bitwise operator and a part of a block
definition. This seems worse.
