Thanks, your advice is most helpful and a good first stop-gap.

Still the current state of CTFE is almost not maintainable
  and I would really prefer a clean-slate approach.

SDC benefits extremely from the extra level of indirection, 
however I do understand that SDC and DMD have diffrent goals 
regarding compile-speed.

Also I feel that good code has found it's most beautiful shape 
when it's simplicity makes it inevitable, at least the 
Ctfe-Mechanism has not reached this point yet, imo.
