Please just introduce a function instead. The operator is also less clear ... if I see "$a <=> $b" and do not happen to be familiar with another language implementing this operator, I won't have any idea what it does (the closest thing <=> could be is the equivalence operator from logic, and that's not the case here). On the other hand something like compare($a, $b) is pretty obvious. If there is concern about clashing with user-defined functions, lets namespace it. A function can also be directly used as a callback. Furthermore a function would fit in well with existing comparison functions like strcmp etc. Nikita Nikita
