One might argue (and on Mondays, Wednesdays, and Fridays I would) that a
standard screen-handling package ought to be oriented towards display of
text rather than video games.  Unless I have missed something -- I am not
all that familiar with curses -- when I insert a line in the middle of my
"screen", curses essentially has to rediscover this by comparing characters.
This seems silly; surely higher-level primitives would be better for most
situations.  (Rogue is a different story, of course.)

Something like the "FastAlpha" package described by HP a couple of Usenixes
ago would be a much better match to text-oriented screen handling, which I
would guess describes the majority of non-game curses applications.  Alas,
curses is already pretty well established; it may be too late to change.
