 So a FUN of the form SYMBOL is equivalent to one of the form (FUN).
 FUN can refer to variables bound earlier in the pattern.
-FUN is assumed to be pure, i.e. it can be dropped if its result is not used,
-and two identical calls can be merged into one.
 E.g. you can match pairs where the cdr is larger than the car with a pattern
 like \\=`(,a . ,(pred (< a))) or, with more checks:
 \\=`(,(and a (pred numberp)) . ,(and (pred numberp) (pred (< a))))

 Additional patterns can be defined via `pcase-defmacro'.
