Granted, but this still doesn't bring you back that single nice
machine instruction it would be in the case of litlits. OK, OK,
this is an O(1) optimization and going via C is bad, but sometimes
it's more efficient to be a bad boy... ;-)

And if you need a tool (which I desperately would), it can produce
the constants right away, without any foreign import. Hmmm, how
does this fit with Green Card? And the tool would seem conspicuously
like a cut-down version of Manuel's C->HS.
