haskell-cafe, you are listed as the maintainer of the vim haskell syntax highlighting script. :-) lhaskell.vim uses the tex.vim syntax script, which does "set iskeyword-=_". This makes editing haskell rather uncomfortable (eg, the '*' command doesn't work right). I don't know what breaks if you "set iskeyword+=_", but getting tex highlighting right is less important than haskell editing, so I suggest this patch.
