[Tolk] `bool` type (-1/0 int under the hood) 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). 2025-01-13 08:21:24 +00:00			`fun failMathOnBoolean(c: cell) {`
