It would be nice, if you can use some mathematical sets in if conditions. This would help to filter input values like integers, string and floats.

Normal representation -> if ($input >= 0 && $input <= 2)
Math. Set representation -> if ($input === [0; 2])

You can use braces (but they are used in PHP) to represent sets of string or numbers like -> colors === {'red', 'blue', 'yellow'}

There is also an international standard (ISO 31-11) that defines sets (
