NOTE(allen): Things I learned from this experiment.
First of all the batch edits aren't too bad, but I think
there could be a single system that I run that through that
knows how to build the batch edit from slightly higher level
information. For instance the idea in point 2.
Secondly I definitely believe I need some sort of "mini-buffer"
concept where a view sends commands so that things like
pasting still work. Then the contents of the "mini-buffer"
can be used to complete the edits at all cursor points.
This doesn't answer all questions, because somehow backspace
still wants to work for multi-lines even when the "mini-buffer"
is emtpy. Such a system would also make it possible to send
paste commands and cursor navigation to interactive bars.
Thirdly any system like this will probably not want to
operate through the co-routine system, because that makes
sending these commands to the "mini-buffer" much more
difficult.
Fourthly I desperately need some way to do multi-highlighting
multi-cursor showing but it is unclear to me how to do that
conveniently. Since this won't exist inside a coroutine
what does such an API even look like??? It's clear to me now
that I may need to start pushing for the view routine before
I am even able to support the GUI. Because that will set up the
system to allow me to think about the problem in more ways.
Finally I have decided not to pursue this direction any more,
it just seems like the wrong way to do it, so I'll stop without
doing multi-cursor for now.
