I can talk from first hand experience here, as SDC uses ONLY JIT 
for CTFE.

It turns out that it is slower in the general case where you some 
small computation, but way faster as soon as you run something 
non trivial.

I don't think it would be a good move to integrate it as this, 
but coupled with some heuristic, it would be great.
