What would be nice about this, is that then you could use "return" in a
script to stop execution. I don't like "exit", because you can't trap
it, if ever you wrap the code in another script.
open OUT, ">do.pl";
print OUT "exit\n";
close OUT;
print "before\n";
do "do.pl";
print "after\n";
Or, "die" should have a way of stopping the program without a warning
message.
