Being able to have different comment definition for headings would be very valuable.
I also like the idea that headings become different than code.  This is because, you
could collapse code independently of headers.  Currently code structures are being
used as headers, a strategy which is faulty from my point of view.

Currently the major problem is in being able to got a good outline-heading-alist
that does the job.  In texinfo.el there is an example on using  outline-heading-alist,
but when I tried doing the same, the headings were not being recognised.
