The first part of this paragraph is not a proposal. It describes
how `history-length' already uses the property of the history symbol.
The Lisp code of `add-to-history' Kim submitted to this list,
demonstrates very simple implementation of this functionality as:
(or (get history-var 'history-length) history-length)
I proposed to do the same for history-delete-duplicates,
i.e. to use the following condition in `add-to-history':
(or (get history-var 'history-delete-duplicates)
history-delete-duplicates)
So my proposal is not very complex, and I don't think Richard replied to
my email.
Well, as I said, I do not understand what Richard was referring to - that's
why I asked. He mentioned a proposal "involving properties to control
lengths. It was very complex."
Your proposal involves properties to control lengths. Mine doesn't have
anything to do with that, and I don't see anything else in the thread about
that. I can't speak to the complexity of your proposal, but mine seems
trivial to implement, understand, use, and document.
I guess we'll just have to wait until Richard decides to enlightens us as to
what he meant.
