`custom-set-faces' is a function that applies a list of face specs. And
this:

    (cperl-array-face ((t (:foreground "yellow" :weight bold))))

is a face spec, where `cperl-array-face' is the name of the face and the
rest specifies how that face will look. The face spec is data (a list),
it doesn't do anything on its own. That's why it's quoted.

That doesn't seem right. The expression (cperl-dark-background nil) by
itself would call a function `cperl-dark-background' with the argument
nil, which won't work as there is no such function
`cperl-dark-background'. It's a variable, so you would use something
like (custom-set-variables '(cperl-dark-background nil)) or
(setq cperl-dark-foreground nil).
