I'm almost at feature parity with the original fast_float, at which point I plan to submit it. (Within the next month or so, if I manage to keep working at it reasonably steadily.) This version would have interpreters for C doubles (like the existing fast_float), MPFR, and Python objects. It's also significantly faster than the existing fast_float interpreter. It will not yet support the extra features I was promising (conditionals, common subexpression elimination); I also plan to eventually add special handling for a lot more types.
