It's funny you should say that.  I was kidding with Kris in IRC last week about how you could just slap a copy of 
DMDScript in the compiler and let us talk to it directly from within templates.  While this isn't letting us muck about 
with the AST, to create specalized grammars, this is certainly a more elegant solution.

... and it doesn't even require a separate syntax.
