I'm just back from a party so I may be, eh, a little bit drunk ;-)
but I really don't see the problem.
An identifier in Haskell cannot begin with a ' so if a
"could-be-identifier" ;-) starts with a ' it is a character constant.
It is completely parallel to digits AFAICS: An identifier may
contain digits, but it cannot begin with one.
So a "could-be-identifier" beginning with a digit is a number.
