That would be the smart thing to do, but long long does exist. IHMO, if you 
don't care about the size of an integral type in C/C++, you use int. Otherwise, 
you use a type that specifices it's size and is _guaranteed_ to be that size on 
all systems. Using types like long and long long is just asking for it. 
Fortunately, D specifies the size of its types, so that isn't a problem.
