The problem is how to prevent the moduleinfo from getting linked in. 
Though this is a general problem, not specific to CTFE.

One thing I have been considering is, if a template is only ever 
instantiated in CTFE (eg in a static if, or while defining an enum 
value), should it still get written into the obj file? I don't think it 
is ever necessary, and discarding it would save a lot of space and time.
