What do you mean by "cross-platform floating-point," using the 
same implementation everywhere without calling _any_ libc/arch 
intrinsics?

How does that differ from the current implementation?

Btw, do you know some way to get the current compile-time real's 
precision in D code? It would be useful to avoid static asserts 
from overflowing when the runtime real's precision exceeds the 
compile-time real's precision, which doesn't happen with dmd but 
can with ldc:
