safe operations - `a === b` => `a == b` - `a + -b` => `a - b` - `-a + b` => `b - a` - `a+ +b` => `+b+a` associative operations (bit-wise operations are safe, otherwise `unsafe_math`) - `a + (b + c)` => `(a + b) + c` - `(n + 2) + 3` => `5 + n` - `(2 * n) * 3` => `6 * n` - `(a | 1) | (2 | d)` => `(3 | a) | b` fixes #412
