You need ghc-6.8.2, the latest yi from darcs

  darcs get http://code.haskell.org/yi

as well as the latest version of fingertree and vty or gtk.  If you have
further question please use the yi-devel mailing list
(http://groups.google.com/group/yi-devel).

Note though, that yi is not ready for regular use, yet.  But, of course,
contributions are accepted anytime.

Not anytime soon (if ever).  It's not guaranteed to be faster in any
case, but its generally faster for bigger inputs.

If you're worried about literals, that's not a problem anymore.  You can
just use:

  myErrorMsg = "Oops!" :: ByteString

Good luck!
