Once upon a long ago (~10y) we already
had this discussion with respect to the
`Partial' module.
Back then someone (probably more knowledgeable)
convinced me that folding floats and doubles
involves all kinds of non-portability issues,
and therefore is potentially dangerous.
E.g.
* What about IEEE-754 (non-)compliance of the
target?
* How do different rounding modes when folding
w/CIL and when running on the actual target
influence code flow?
This was the reason, why I left the code alone.
HTH,
