There's no reason it would require wrapped arguments. The input types are
known from the static low-level function type, so the JIT compiler can just
work with them and adapt the function that is being called.
These things are trickier in a non-JIT environment, but we are currently
working on a general framework to support low-level calls through the
CPython ecosystem (I mentioned that before).
