That sure isn't what I wanted!

I tried to write:

system ( "$cmd" ) == 0
	or warn ( unless ($QUIET) { warn "failed remote copy: $!";});

but perl doesn't like that. I have to do:

if ( system("$cmd") ) {
        warn "failed remote copy: $!" unless $QUIET;

Why is unless so picky about where it is?

Einstein himself said that God doesn't roll dice. But he was wrong. And
in fact, anyone who has played role-playing games knows that God
probably had to roll quite a few dice to come up with a character like
Einstein.  -- Larry Wall                                     C. Abney
