No, this doesn't quite cut it for debugging CTFE functions: While you
can obviously use pragma(msg, …) to write the *result* of a function
invoked via CTFE to standard output, this doesn't help you if you want
to debug the stuff going on *in* that function itself, for example to
track down one of the numerous CTFE bugs.

P.S.: As a last resort to get something printed during CTFE evaluation,
it is possible to use »assert(false, message)« – DMD prints the
(correctly evaluated) message as part of the compiler error message.
Obviously, this screws up compilation though.
