in reply to Modulo operation to return quotient and remainder
While many modern CPU instruction sets support getting quotient and remainder in a single operation, nearly no high-level programming languages support it. Not even C (unless via embedded assembler).
In Perl, the overhead of a single subroutine call is probably much bigger than simply performing two separate operations, so from a performance point of view, you shouldn't bother.
If you are after convenience, it's easy enough to write a subroutine yourself that does it.
