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 :)
