I tried to mimic the getkey() function, but I like your idea. In many cases
you don't have to check explicitly the type. Example: if key == "q":
quit(), or if key == curses.KEY_UP: move(1). It works also if the key is
used as a key of a dictionary: key => callback. And yes, keyname() can be
used to mimic manually getkey() behaviour.
It does not solve unget_wch() issue, but I propose to drop the
unget_wch()+get_wch() test on non-ASCII keys because it looks like a bug in
the curses library.
