I have a couple more ideas, here's one of them:
- if a function is pure and called with constexpr parameters, the 
compiler could potentially execute that call in the CTFE engine 
(automatically), as part of the constant-folding phase I guess. 
Such a technique will hopefully one day be practical, once the 
CTFE engine's performance improves.
