I wish I'd taken the mic at the end, and 2 days later Adam D. 
Ruppe said what I was thinking of saying: unit test and debug the 
CTFE function at runtime and then use it at compile-time when 
it's ready for production.

Yes, Dmitry brought up compiler bugs. But if you write a 
compile-time UT and it fails, you'll know it wasn't because of 
your own code because the run-time ones still pass.

Maybe there's still a place for something more than pragma msg, 
but I'd definitely advocate for the above at least in the 
beginning. If anything, easier ways to write compile-time UTs 
would be, to me, preferable to a compile-time printf.
