Looking at the size of my prime executable, it was around 800

Why is such a short program resulting in a so big binary?
That's probably basic these compilers statically link the runtime
(and standard?) libraries by default. Compiling your program with
`ldc2 -O3`, I get a binary of 28K, and stripping gets it down to
17K.
