 		770279e02d Arithmetic expressions (#1083) 
Add support for arithmetic operators:

- Unary `+`.
- Binary `+`, `-`, `*`, `/`, `%`.

Specify their behavior for integer and floating-point types. Signed integer overflow is a programming error, handled in various ways. Unsigned integer overflow is specified as wrapping around, intended for hashing / crypto / PRNG use cases.
