one can set the environment variables

Not so easy to do. When run a Perl script gets its own copy of the system environment. It can't directly change the system's copy of environment variables so it can't easily set changes that will be seen by other scripts unless they are forked from the parent script (and thus inherit the parent's environment).

Premature optimization is the root of all job security
