Re: Better parse-partial-sexp; multiple major modes (was: Idea for syntax-ppss)

[Richard M. Stallman]

    Maybe a core solution could be something like this: in a given buffer,  
    each character has a chunk-name character property. You'd buffer- 
    locally map chunk names to major modes. For each chunk name, create a  
    buffer containing just the text assigned to that chunk.

That is elegant but very expensive.  Making so many buffers display as
one buffer, or keeping them in sync, would mean major changes at a low
level.  Even coming up with a spec for how insertion and deletion should
work in such a scheme is hard.

We are much better off with MuMaMo.
