Although I'm a fan of --with-wide-int, I don't think it should > force this extra complication in modules. I managed to make it work for --with-wide-int without having to re-compile the modules (those rare 64bit values which can't be crammed into 32bit go through an extra proxy object). That imposes an extra cost in the module-API for the wide-int case, but this cost should still be smaller than what we had before (since in 99.9% of the cases, the conversion 64<=>32 is just a matter of shuffling bits).
