I think the main thing that's still done in C is the floating point

Would be great if a contributor could translate FP parsing and
formatting code into D. Then we can use it in CTFE. I need it badly
for some function tabulation code.
I think formatting cannot be done such that it is CTFE-able. I tried
implementing a less-inefficient version. As far as I can tell at some
point you need to extract the significand and the exponent. This is done
by some "unsafe" cast which is not allowed in CTFE. I don't know a way
to do it in CTFE-compatible way.

Yeah, I think I will have to find a way of allowing it. But it's
difficult to see a clean way of doing it.
