So you don't have to switch buffers (and mental context).  Most of the
time in C I'm flipping between a .h and a .c file.  This feature would
work well for *short* includes, IMO.  With long includes you lose
context and nothing is gained.

I would make an analogy here to Literate Programming, where you
interweave documentation within the code.  We're talking about
interweaving included snippets to build a dynamic whole.

RS> What does it look like, to have multiple files in one buffer?

That's a UI design question and could be up to the implementation, not
in Emacs.  I personally would like something akin to a folding editor
with clear delineation (maybe statically indented N spaces, like your
quotations) but would have to experiment to find the best interface.
It's definitely not going to look like anything we have today.
