And when would you use this?

D has alias, so you all you need is a feature that allows you to 
query what is compiled to hardware instructions and what is 
compiled to software, then bind it.

This what actual production code does in C/C++ too. If you are 
flexible about precision you typically bind it to an alias. E.g. 
in signal processing you might bind "sample_t" to a known fixed 
floating point type in your configuration header.
