## Message

```
Sema: improved comptime `%` syntax

 * comptime known 0 as a numerator returns comptime 0 independent of
   denominator.
 * negative numerator and denominator are allowed when the remainder is
   zero because that means the modulus would be also zero.
 * organize math behavior tests

```
