Do you want support for CTFE coverage ?

[ketmar via Digitalmars-d]

there is no need in that, absolutely. CTFE is undebugabble anyway 
(and pragma(msg) not really helps -- i'm saying that as a fan of 
printf debugger), unittesting it is silly and so on.

after all, as CTFE *should* behave the same if it is done in 
runtime, one can always test and debug CTFE code as "normal" code 
before using.

so, i say: "don't bother".
