Template metaprogramming == "abuse the template facility in C++ 
to run a program in compile time" used to be the only way to 
execute something at compile time in C++. In D you don't want to 
do that as writing such code is a matter of putting an enum or 
static at the right place. Still, you can use templates to 
achieve your goal, if that helps.
