It's not just significant indentation. CS parses "f + g" differently from "f +g" (the former is an addition, the latter is a function call with "+g" as the first argument).

Yeah, the unary operators can cause gotchas.

Also, here's a gotcha I've run into where `a(b)` is considered different from `a (b)`

x a(b), c # => x(a(b), c);

x a (b), c # => x(a(b, c));
