Thanks for the nice bug report. It looks like you're probably using haskell-mode 2.0 (the packaged version). Apparently there's a bug for xemacs in lhs mode. It works fine in gnu emacs. I don't think this is related to the warning you get.
The message about turn-on-haskell-font-lock is just a warning, and it looks like it can be safely ignored. It doesn't look like the two packages are interacting badly except for generating one warning, so I wouldn't worry about that. The xemacs version (1.43) is an older version and doesn't work quite as well for certain highlighting and indentation things. A couple of workarounds for your .lhs bug: - remove haskell-mode. You'll then be using the older, built-in version from xemacs, which doesn't exhibit this bug. - use gnu emacs, where this bug doesn't seem to appear. I'll alert upstream about the .lhs bug in haskell-mode 2.0. peace, isaac -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
