but that's what qx() or the backticks are for (personally, I like qx() more).

I understand what you're trying to say, but some beginners reading this might think backticks and qx() are two different things. Backticks and qx() are the same. qx() is an operator, `` is its shorthand. In fact, any non-whitespace character can be used as a delimiter (if it's alphanumeric, whitespace before the delimiter is required). qx() is not a function - my $dir = qx("ls -l") will probably not do what you want.

`ls -l`
qx(ls -l)
qx[ls -l]
qx`ls -l`
qx$ls -l$
qx!ls -l!
qx nls -ln
