Maxima rationals compared to CL rationals

I agree that allowing CL rational numbers (and CL double floats)
to be valid Maxima expression would be nice. But it wouldn't fix any
bugs, it wouldn't extend user functionality, and it would make GCL
Maxima run more slowly (maybe the GCL slowness problem could be easily
fixed). And such a change might cause little bugs years after the
change. It's hardly worth mentioning, but allowing CL rationals
would break some (maybe a great deal of) Macsyma code.

But if somebody wants to try, that's great.
