No, the other way around. All those `foreach` functions are supposed to return the amount of targets the passed function was successfully applied to, and to do so rely on the return value of said function (and sum the return values).
As such, functions to be used with foreach, should always return a number (and it should be 0 if nothing happened, or 1 if the function was successfully applied). In some cases you can simply return 0 or return 1, but that's a bad practice. Always return 0 if nothing was done, and 1 if something was done.
