I want to pass an integer to a sub. The only valid values of the integer are 1, 2, 4, 8, and 16. Other than using "if" to test their values, is there a way to state that an integer can only have certain predefined values?
I like this syntax:
sub MAIN(Int $value where $value ∈ <1 2 4 8 16 >) {
....
}
It is readable and I really like to use the '∈' symbol :D.
Cheers!
