Subject: 29.0.50; Wishlist: thingatpt should use fields
Date: Wed, 22 Dec 2021 14:00:21 +0100

A previous attempt at making this happen was done in
7db376e560448e61485ba054def8c82b21f33d6a, but was reverted due to
serious performance regressions (see bug#52593).

I still think it's a good idea to make this work, but it has to be more
efficient.  Perhaps a way to implement this would be to make the
beginning-of-thing/end-of-thing functions (or something in that
vicinity) check whether there's a field in the area it's covering, and
then limit itself to that area first.

That should fix the performance regressions -- the problem with
just calling field-beginning/end without any limits is that it will
search through the entire buffer, and that can be slow.
