Rainer Deyke:
(A function that performs I/O is
obviously not a candidate for CTFE.)
I don't fully agree, see this enhancement request of mine:

"performs I/O" refers to the semantics of the running program; the I/O is
done at the time the function is invoked. I/O done by pragma(msg, ...) or
ctputs is performed by the compiler, not by the function. Obviously, as
Rainer said, no CTFE function can perform I/O since that I/O would never get
performed by the running program.
Also, I think computing compile-time messages is an abuse of CTFE -- it
certainly isn't its intended purpose.
