Yes, I know about these as well. The first would normally be
addressed by
(add-hook 'haskell-mode-hook
(lambda ()
(modify-syntax-entry ?\\ "'")))
but of course this screws up parsing of strings, which will now be
terminated by \" :-(
The second one is because the haskell mode tries to handle comments on
its own (and fails), since once again Haskell comments can't be
handled by the normal mechanism -- partly because of nested comments,
but even the line tail comments are weird due to the single-token
rule.
All this taken together, I mean, _really_, is the lexical structure of
Haskell a botch, or what?
