Comparison operators `== / >= /...` return `bool`. Logical operators `&& ||` return bool. Constants `true` and `false` have the `bool` type. Lots of stdlib functions return `bool`, not `int`. Operator `!x` supports both `int` and `bool`. Condition of `if` accepts both `int` and `bool`. Arithmetic operators are restricted to integers. Logical `&&` and `||` accept both `bool` and `int`. No arithmetic operations with bools allowed (only bitwise and logical).
