a “walking stick” is a stick that is used for walking, or a “thinking cap” is a cap for thinking.

By contrast, those patterns don't "help" destructuring in any way I could spot.
Surely they do: they provide the whole destructuring logic, in a declarative way. pcase then simply interprets it according to its rules.
