Language-level Alias - bool
The boolean type in Julian language. There are only two values for this type: true and false.
Bool type can participate in boolean operations such as '&&', '||' and '!'. It can aslo be concatenated to string value with '+' operator in the literal form of this value, 'true' or 'false'.
Bool is a primitive type. Therefore it can only be assigned to a variable with same type or an untyped variable.
