 If I press the up or down arrow keys, GHC kicks in and makes it so that
 the last line of text comes back instead of letting me intercept the arrow
 key. From what I have seen, you need third-party libraries to override the
 default behavior, but when would a user actually want that behavior in an
 application instead of letting the programmer handle it? Can there be a
 switch (like a special LANGUAGE pragma or whatever) to enable raw input
 capture?
 Console text editing applications are greatly hindered by this automatic
 behavior.
