Is there any preprocessor scripting language?

[MarisaLovesUsAll via Digitalmars-d]

I just want to write something like this:

#ololo script
     foreach(child; findAllChildrens())
     {
         child.insert(
             static void doABarrelRoll() { }
         );
     }
#end

Templates/mixins is not enough for me... maybe because of 
hands.dll error :)
