If space sensitivity or () disambiguation is being used on !, could one of these also be permitted on ~ to permit it as a valid infix term-level operator?
I don't think there's any reason ~ couldn't be an operator, defined with the (~) x y = ... syntax. Allowing it to be defined with infix syntax would be a little trickier. Hmm, I've just realised that if we decide to make !_ and !foo lexemes, then we'd also want !(+) to be a lexeme, which presumably means we'd want (+) to be a single lexeme too (and also `foo`, for consistency). But I don't think making that change would be problematic. Thanks Ian
