Re: Bugs caused by recent use of define-derived-mode

[Luc Teirlinck]

Actually, I thought a little bit about inheritance or
inheritance-mimicking and maybe the main abbrev part of the problem
might be easier than I thought.  The solution I have in mind would
perfectly mimic true inheritance, regardless of whether the internal
implementation could be called "true inheritance".  It would use
pre-abbrev-expand-hook to check whether updating the abbrev-table is
necessary and update it if it is.  It is very similar to what
mailabbrev.el does, but actually simpler.  I am still not sure that
inheritance is really that desirable, but if it is decided that it is,
then I might be willing to implement the main abbrev part of the
problem as long as somebody else would rewrite list-abbrevs and take
care of similar "obvious details".  I have currently no time to do so.

Sincerely,

Luc.
