Ostensibly the function is trivial:
bool msg(string) { return true; }
It doesn't change the semantics. The compiler would recognize it as an intrinsic
and would print the message if the clause to its left has failed.
There was a proposal a while back to enable CTFE to print messages, which is
probably a better solution. msg() could be something along the lines of:
bool msg(string) { __ctfeprint(string); return true; }
which would involve considerably less compiler magic. Furthermore, `msg` could
be a local private function, which would avoid "but I'm already using `msg`"
problems.
