Is there an official place to send bug reports to?
There are several bugs in the lex function specified in the PreludeText
section of the Standard Prelude for Haskell 1.4. To start with the subsidiary
function lexLitChar is not defined. Also there is a typo isAlphaNum instead
of isAlphanum (this typo also appears on page 34 of the Standard Libraries
report). There are I suspect some further bugs too. Also Hugs does not lex
the backquote character as specified in the definition.
More generally, I wonder why this is in the Prelude rather than a library
where it would seem more appropriate?
