You don't lose the type and blessed information, per se. The address, when turned back into a reference, regains that data, if you do it the way I did it in my XS code: RETVAL = newRV((SV *) addr); Doing it like that restores the reference fully.

What I don't get, though, is what this is good for. The memory for the data structure must still be allocated. In which case, why not just use a reference (which is an SV) instead of a number stored in an SV?
