Nice.  What is prior art in this area?  I know of

though I never used it myself and don't know its status.  If it
already has adoption in the lua community, it makes sense to use it
and make sure it can be compiled against our curses.  Though that may
be less fun that writing your own from scratch :)

It would be nice to be able to use the same lua binding with both our
curses and ncurses.  I have a simple screen grabber based on a
rumpified wsvt25 that I wrote to test and debug the kernel terminal
emulator(*) and it might be tempting to co-opt it as both wsvt25 *and*
curses test bed (I know, Brett doesn't like the screen grab approach,
but I think it has its place :).  Being able to run the same test with
ncurses and our curses and compare results will be handy.
