Curses is much more than that, though. One cool feature is its redraw
optimizations -- do a lot of changes, and call a "commit"-type method,
and curses chooses the most optimal (for your terminal) way of changing
the display according to your wishes.

If it should be done, it should be done as a compatible subset of
curses, IMHO. It has such a long history as the standard "GUI toolkit"
for text terminals.

  import curses
except ImportError:
  import inferior_curses as curses
