| 2.2. Identifiers can use small and large Unicode letters.
| What about caseless scripts where letters are neither small
| nor large? The description of module Char says: "For the
| purposes of Haskell, any alphabetic character which is not
| lower case is treated as upper case (Unicode actually has
| three cases: upper, lower and title)". This suggests that the
| only anomaly is that titlecase letters are considered
| uppercase. But what is actually specified is that caseless
| scripts can be used to write constructor names, but not to
| variable names. I don't know how to solve this.
I am woefully ignorant of Unicode, and I have no idea what to do about
this
one. I therefore propose to do nothing on the grounds that I might
easily
make matters worse.
