Many examples in the patch, have you looked?

Pcase it extensible for any object structure the user may
think of you can think of. This proposal is an extension.
Here's an example
(pcase some-mistery-object
((cl-arglist (42 &key a b c)) ; this proposal
(message "Oh, it starts it 42 and has c=%s" c))
(`(,_ ,x ,_)
(message "Boring three-element list with middle %s" x))
(`[,_ ,x ,_]
(message "Fancy vector with middle %s" x))
((franklinboing (nixneez)) ; my data-structure
(message "This franklinboing has some nice nixneez %s=" nizneez)))
