I was reading over some code that used the MIDI module, and saw the
C method. I began wondering, how does one report the
error if he feels like it, but let the module report the error if not,
in a concise way.
What about something along the lines of a C statement modifier,

Is that C or C ?
It's C, which is low precedence C.
And if so, what's C and where can I find more on it?

Hmm. I think I may have missed Luke's point. Which was (presumably):
what if C<$opus.write_to_file($file);> validly returns C?
In which case I think we just fall back to:
try{$opus.write_to_file($file); CATCH {die "Couldn't write to $file: $!"}}
which is, after all, only 5 characters long
