Yes. 1.0 is not an exact number. What's wrong with that?
(Consider stuff like 0.333333333*3: this shouldn't be exact!)

I haven't mentioned anything about implementation, so I haven't dealt
with the C level at all. Currently, a Python-level API is under 
consideration. I believe I can keep current day C API almost unchanged.

I shamelessly stole it from Scheme, with only minor changes -- most
of them about hardening some things Scheme left for implementations
to decide.
