In D, you can run regular runtime code at compile time in a lot 
of cases. Just write an ordinary function that returns the data 
you need, then use it in a static variable initialization.

// example function, notice regular if and variables inside
int calculate(int i) { if(i < 0) return -i; else return i; }


static int value = calculate(5); // this is run at compile time



Ordinary functions will be interpreted if asked for their result 
in a context that only can be run at compile time, like a static 
variable initialization or inside a static if.
