Agreed. I think the remove syntax is all but unreadable:
(setf (alist-get KEY LIST t t) t)
to remove items from LIST with key eq to KEY.
Unless accompanied by comments, I do not think that meaning obvious
at all.
This variant gives a better idea...
(setf (alist-get KEY LIST :remove :remove) :remove)
I struggle to imagine a scenario where I wouldn't use some more
explicit syntax for deletion, though; even when the decision to
remove or not is being arrived at dynamically.
