Special type wrapping an opaque pointer

Not exposed to the language yet. Do something like:

extern fun somethingCustom() > ud;

ud userData = somethingCustom();

Later we could allow to define a user type for specific user data:

extern fun somethingCustom() > ud(Info);

ud(Info) info = somethingCustom();
ud willFail = somethingCustom(); | would fail
