> The "quickfix" I installed on `emacs-30` should not suffer from
> a significant slowdown, no, so I think we're good for `emacs-30`.

> The "better" fix I installed on `master`, may still cause a bit of
> sluggishness with eldoc, OTOH.

> I think the "right" fix for that is to extend `documentation` or `C-h f`
> such that the `pcase` doc can distinguish between the (quick to
> generate) doc about `pcase` itself and the table of Pcase patterns
> defined with `pcase-defmacro` which is appended to the end of the
> `pcase` doc (and which can take a bit of time to generate but is not
> needed for eldoc).
> 
> It would also be good to be able to show the table in a kind of
> abbreviated form (one line per Pcase pattern) with a way to
> unfold/refold specific patterns' doc.
> 
> The same applies to the list of methods displayed in the doc of generic
> functions and in the doc of types.

Should we now close this bug?
