I wasn't aware of this.  Last time I looked was Unicode 3.0.  Thanks
for the update.

I'll concede that String and [Char] are identical as far as the
programmer is concerned. :-)

There was some research 10+ years ago about alternative representations
for lists which were semantically identical but a little more efficient
in memory use.  Even if you don't go that far (it is fiddly), constant
strings, for example, could be representable as UTF-16/UTF-8/whatever
along with some machinery to generate the list on demand.  Char objects
could be implemented as flyweights.  Lots of possibilities.
