I would be concerned about the performance impact of having to go 
through function calls for functions that are really macros, especially 
on platforms with built-in float16. Perhaps we could still use macros on 
those platforms.


We would have to check the benchmarks of consumers of the npymath 
library for impact. Do we know of consumers other than SciPy?
