I don't know if you saw the thread about infix in wart[1], but I can say:
def (y x)
(m*x + b)
All operators have the same precedence, but operators without whitespace have precedence over operators with whitespace:
(n * n-1)
The major drawback is, of course, that you can no longer use '* or '- in symbols. I use capitalization for globals and underscores in long names, and have been mulling camelCase.
(Wait, didn't someone check the pitchforks at the door?)
