I just read that D fits nicely to the 64-bit architecture. Is there currently a D compiler that fully exploits the 64-bit hardware under Windows 7? I mean e.g. one can have operations in D on unsigned long int of 64 bits size that correspond directly to hardware operations so as to achieve high efficiency? (Sorry for my ignorant's question, I don't know yet the language.) Thanks in advance.
