Just for reference, this isn't any better a solution to providing a
portable "use the default Perl" than the previous statement: some
operating systems only provide /bin/env, which makes it also fail...

It does, as noted, ensure that if your admin has installed multiple
versions of Perl it will pick the same default as running the command
interactively -- which, also, may not be the "system default" perl if
the path is not set in, eg, the environment of a cron job.
