We kinda-sorta can, with `lazy void`. If we could get the code 
out of it as a string, that might be interesting. But I don't 
think it would hit the interp thing (whose library implementation 
is really just the mixin expression on the outside)

Keep in mind that mixin templates currently do not actually need 
arguments listed.
