I do understand that the approach you propose is indeed used, for
example, for `car' in emit_lval_XCAR. However, is it practical for
functions like `floor'?
`car' implementation is very unlikely to change in future. But `floor'
and other functions (we should not be limited to `floor') may change
their implementations. The extra "native comp" copy of the
implementation will need to be always synchronized with the original
implementation. I doubt that it is practical maintenance-wise.
