      yeah, but it satisfies the OP's implied set of integer values given by x=x+5 | {0, 5, 10, 15, 20, 25, ...}

        Yes, it matches all the valid inputs, but it also matches various invalid inputs.

        If all you care about is matching valid inputs and don't care about matching invalid ones, you can just do:

        if (1) { ...; }
