- compile time hackery like meta programming. Eg have a look at haxes or
Scalas macro feature which allows generate ast at compile time.
Haskell template haskell system is similar.
Simple use cases are
db.query("SELECT a,b FROM foo") and have the compile type check the
query and the derive the result type for instance.
But of course there are many more.
- also allow pure functional style (maybe lazy like Haskell, maybe not)
- maybe some record typing (like impredicative.com/ur?)
- using different memory management systems
- type classes (like Haskell etc) stuff like that.

Again - this will always be very very very hard. Yzis failed. And that
was a "rewrite", see here: http://www.freehackers.org/VimIntegration
Read this carefully.

No, because Zimbu is yet another language which will only be used by
Vim. I want to think more about this choice before starting to rewrite an
editor - after all Vim does work in its current state.

Well - there is more work to be done. Eg "Yi" is a rewrite (written in
Haskell). Before starting big undertaking we should know what we want
and why.

Community already does - I mean people are switching to Emacs.

So let's think harder about the programming language first, please.

It doesn't matter. Forums suck, too.
You need both: Forum and/or mailinglist for discussion *and* a wiki like
thing to record the summary. Everything else will become tiresome soon.
Please stop thinking that "just starting to rewrite an editor" will
solve all issues. You need kind of design, and that does not exist yet.
You must be able to know why you don't just add "Vim" like mode to jedit
instead of rewriting an editor from scratch, or join Emacs (evil mode)
etc.
And you must learn that writing a new editor will take a lot of time.
Have a look at history of either Vim, Emacs, jedit, ...
We're talking about a couple of years eventually.
