On Windows32 DMD produces binaries for small programs that are
often half the size of binaries generated by similar small C++
programs compiled with G++ (about 300+ against 700+).
D has a garbage collector, runtime type introspection (module
info, type info, etc), run-time built-in operations on dynamic
arrays (concat, append), associative arrays and some of their
operations, a sort (but probably the built-in sort and reverse
will be deprecated and later removed), exceptions, and more. All
that needs space that's absent in the C++ binary.

And then you will need the GC somewhere to run it :-) Both static
and dynamic linking have their advantages and disadvantages. I
think Go has a storng preference for static linking.
