Re: Is Elisp really that slow?

Hi Stefan:

I agree with you about the prefix. After some suggestions in private
(from this same thread) I have been using the composable package [1] and
it works like a charm.

I didn't use it before because I didn't know about it (it is in
melpa). But it really improves the emacs editing experience a lot
without affecting the default behavior. It has the best of modal editing
(the consistency) but without the annoying modes.

There are some missing details, and things that can be improved, but I
see a lot of potential there. Probably this package (or a similar
design/reimplementation) may finish with the arguments about vim's modal
editing vs emacs memorize command and inconsistencies. Because it
provides the best of both worlds. It is compatible with transient and
delete-selection modes.

The same applies to some commands and functions that will be not needed
anymore (or needed to remember) as explained in the project's Readme.
