Two more puzzling questions for patchlevel 18:

1. Why does this construct not do what I think it should?

	exec "/non-existent-file" || die "Can't exec: $!\n";

2. Why does this construct not work when this script is called
   from cron?

	#!/usr/local/bin/perl
	eval "exec /usr/local/bin/perl -S $0 $*"
		if $running_under_some_shell;

   The output here is a message from cron, saying:

	sh: <first_file_in_home_directory>: execute permission denied

   (or something like that).
