You did not provide any justification. As you do so keep in mind a lot
of code is going to look like:
if (is_countable($arg)) {
/* take a different code path, such as pre-allocating storage */
}
This is not an easily reflectable thing because it's based on an
argument which may not even be an object type. Additionally we have a
well-established convention of `is_*` function for types specifically
known to the engine as is the case here.
