Outermost function when using $ operator isn't parsed as a function

When I have multiple functions chained together using the $ operator, the outermost function doesn’t get highlighted as a function.

The problem

Here is my code:

exactMatches :: Code -> Code -> Int
exactMatches actualPegs guessPegs =
    length $ filter foundMatch $ zip actualPegs guessPegs where
        foundMatch :: (Peg, Peg) -> Bool
        foundMatch (actual, guess) = actual == guess

Here is what it looks like with the onedark.nvim colorscheme in neovim: The outermost function, length, is not highlighted the same color as the functions filter and zip. So, I suspect that tree-sitter isn’t parsing it as a function.

Expected behavior

I expected length to be highlighted the same color as other functions. When I use parentheses instead, length is highlighted correctly.

I guess it would make sense to synchronize the queries from nivim-treesitter…go ahead if you like!

yep!
