Whew! You had me worried my code had unicode bugs.
I phrased it as "*alias* for backward compatibility" for a reason. It should be the same thing, but I expect older versions of Haskell used the older name because it was well established in the pre-Unicode era. (I couldn't say whether it was ever *native*; Haskell did not evolve in a vacuum, there are other languages in its background.) -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms
