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: $!";
