I would be very happy to have that in D. That idea is super cool 
and I've never even thought that was a problem to be solved, 
thanks for your input!

I have a plenty of functions that are called in compilation time, 
and beyond reducing the object generation time, one would of 
course get reduced binary size, which is also fairly important to 
those which are targeting WASM.
