;;;; Additional pattern type definitions
+;; Hint: we sometimes need to create (pcase) backquote forms with
+;; backquote. I do this like in this example:
+;;
+;; (let ((y 2))
+;; `(,'\` ((,'\, x) ,y)))
+;; ==> `(,x 2)
+;;
+;; Note that the backslashes are mandatory, else the reader macros are
+;; interpreted as composition of the respective operations, like in
+;;
+;; `(', (+ 1 2)) ==> ('3)
