Well, there's those hardware options, of course. :)

I, for one, am not confident that IEEE arithmetic is perfect.  I am
very confident that the experts who designed that standard will
someday need a new one.

I would like to standardize Scheme's use in such a way that the
language doesn't need to fundamentally change anytime such a change
happens.
