Yeah. If you used printf instead of writeln, the size gets down 
to about 250K (on my linux anyway), which can then be stripped 
down to 160K, showing that the rest of the size comes from 
pulling in a lot of standard library code.

The rest of that 160 K is the druntime library, stuff like thread 
support, memory management, etc. that is always present.

It is possible to strip that out too and make really tiny 
executables (I've gone down to under 3KB before playing with 
this, as have other people working in the embedded space), but 
then you don't get any of the library and it is easier said than 
done.


But you should compare this to other common programming 
language's sizes:

* Java programs need the user to download like 20 MB of the JRE 
to run

* Ditto for the .net/mono frameworks

* The ruby interpreter on my computer is about 18 MB

* etc etc etc


Compared to them, D programs are small. The big difference is 
Java, .net, ruby, python, etc. are already popular enough to have 
their libraries/support code pre-installed on the user's 
computer. D programs, on the other hand, carry all their support 
code with them in each executable (they're statically linked) so 
they have better odds of just working without the user needing to 
install other stuff that they prolly don't already have.
