They're very bad ones. Get the Camel Book and read it (it's actually
quite a fun read, even if the language it describes varies between nasty
and vile).

*Everything*, pretty much, is supported natively.

If you find yourself using system() in perl, you are almost certainly
making a mistake. What with open, IPC::Run, and XS, you pretty much
never need it.

Oh, and it's worth hitting CPAN whenever you think Perl should be able
to do something but can't: the likelihood is that someone else has
already made it do whatever-it-is.
