[Haskell-cafe] Vim + literal Haskell + dollar symbols

[Wolfgang Jeltsch]

Hi, Ivan!
Unfortunately, I cannot reproduce your problem. With my Vim
configuration, I get this: https://ibb.co/e6RLKc. Interestingly, the
syntax hightlighting I get generally looks quite different from the one
you get.
I don’t know how to get a change into Vim’s default syntax/lhaskell.vim.
Also, my patch might not be optimal (it almost duplicates some code).
All the best,
Wolfgang
