that's what I was thinking of, you end up with template at some point. If 
nothing else you get:

char[] CTFEfunc(T)(T t){...}

sweet, will it also do mixin unfolding? this would be where you can expand 
a mixin in the editor to the text it expands to. This would however require 
the ability to pin template parameters and unfold/evaluate that as well. 
Whatever happens, it will be fun to see.

My experience is that template stuff was Greek to me, then after taking programming 
languages, it was a lot clearer. I wish you luck.
