Do you want to take on that job, or shall I? I guess we have no choice
but to loose the history in your repo?

Indeed, for Float's I just use outString (show x) - so having
something proper would be good!

Do you actually have Yhc.ByteCode compiling with Yhc? If its only a
future self-hosting concern I'd just say use Data.Int now, and when we
need to self-host we'll make sure we add it. If its an active issue,
I'll talk to Tom and see what we can do.

Thanks
