Hi guys,

it's your call. But please change the doc string to clarify that pcase-let does not do "symbol equality" pattern matching, but only structural matching. Adding an example like the following will help.

(pcase-let ((`(foo ,x 23 ,y) '(bar 11 baz 22))) (list x y))

All the best

Marco

So I guess we should close this as wontfix?
