Ok, so some comments I wanted to postpone before I summarize them and
formulate better, but you asked.

I quite closely followed each of your Lisp/vim attempts. So I tried
the last one as well. I found that I can use with some (often great)
pain the modified viper mode, and that the coding is probably more
efficient than my previous favourite setup (clisp + modified readline
settings and vim). I love <Space-e>.

The rest of mail contains some detailed complains I recall. I suppose
they all can be fixed, but I dont have time to learn how at the
moment. It's from memory, so I apologize if something is not
completely correct.

I miss Ctrl-P (I use it more often than Ctrl-N, because I tend to
repeat what I wrote above, not below).

I miss Ctrl-X Ctrl-F (and it hurts when it wants to load new file). I
am not sure whether gf works.

:sp used to take an argument on vim, and I used to rely on it,

In lisp repl window, sometimes ":" ceases to work (goes to ex mode,
cant be written into buffer).

I miss visual mode (oh, I see it should work - i tried only V, not v).

I miss =.

Escape works strangely and does not always cause leaving insert mode
(especially Esc-x, seems to behave like Meta-X).
