A good point. It's almost never necessary, and almost always
undesirable, to call a function from the shell. There is usually a way
to do this from withing Perl, and that way is almost always faster and
more secure. Passing stuff to the shell is a good way to have someone
pass a little bit of rm -rf through our script and to the shell.

It might also be interesting and entertaining to look at the Perl Power
Tools, which is a project to rewrite all the standard Unix utilities
(ls, rm, traceroute, and so on) in Perl. This is largely for the benefit
of non-Unix folks, but is mostly for its entertainment value. ("Hey, if
I can't get a date, at least I can rewrite Emacs in Perl!")
