I was thiking the dmd compiler did CTFE without someone ask for 
this, in the way as I've mentioned, checking for constant 
arguments + function's purity and if all this is true, it did the 
CTFE rather than generate code to compute it at run-time. In the 
case of it did happen, I just wanted to know. It was my 
misunderstsooding how it does works in dmd.
