Usage Example

import basics

func main {
    a Letter = letter('a'ub)
    b Letter = letter('b'ub)
    
    printf("%S < %S  =>  %b\n", toString(a), toString(b), a < b)
}

struct Letter (char_code ubyte)

func letter(char_code ubyte) Letter {
    l POD Letter
    l.char_code = char_code
    return l
}

func __less_than__(lhs, rhs Letter) bool {
    return lhs.char_code < rhs.char_code
}

func toString(letter Letter) String {
    return string(&letter.char_code, 1)
}

a < b  =>  true
