The compromise that Larry and I came up with is that I got to keep 
my parens and he got to keep his "or die".

The only remaining problem is that that breaks the lovely parallelism 
of "|| die" on false and "// die" on undef.

    my $line   = <STDIN>		// die "no input on stdin";
    my $kidpid = open(CHILD, "|-") 	// die "cannot fork: $!";
