I don't know that I want stuff in druntime simply because it can be made intrinsic--that's largely a QOI issue for compilers.  If there's a solid justification for a core.math module, that's a different story.  One easy litmus test I use for what belongs in druntime is if druntime itself needs the module to implement some other functionality.  So far, I've seen little need for std-defined math functions in druntime.
