Error when opening a Haskell file

[ghost]

Related to issue travitch/hasksyn#10, the following error occurs when opening a Haskell file:

Error detected while processing /Users/samvv/.vim/plugged/vim-polyglot/syntax/haskell.vim:
line   85:
E59: invalid character after \@
E475: Invalid argument: hsOperator "\(\%^\#\!\)\@!\(\(\<[A-Z]\w*\)\@64<=\.\)\@!\(--\+\([^.%\~\&\*/\$\^|@:+<!>=#!\?]\|$\)\)\@![-.%\~\&\*/\$\^|@:+<!>=#!\?]\+"

Maybe time to switch to another syntax highlighter?

Please suggest some :) Preferably only syntax + indentation

Hmm ... as far as I can tell haskell-vim looks like the best alternative.
