The code at
http://hub.darcs.net/lelf/acme-
lookofdisapproval/browse/Acme/LookOfDisapproval.lhs
is accepted by ghc, but technically, the leading letter of the funny
identifier (Kannada TTHA) is neither lowercase, uppercase, nor titlecase.
It can be accepted in any position of an identifier except the first,
where Haskell requires the character to be either upper/title-case (conid)
or lower (varid).
isLetter x && not (isUpper x) does not imply isLower(x).
