this is a union of a few things

1] my crazy idea to do a compieler in D CTFE
2] Jeff Nowakowski's post in the main D ng about the Unreal Engine

How about a compile time "script to byte code" package? Some sort of VM that 
is totally integrated into your app could use byte code programs that are 
compiled by your engine at compile time.
