['|'] or any list with '|' as its first element stops syntax highlighting for the rest of the document.

This is only a problem with che character '|' as the first element in a list literal, i imagine it has something to do with comprehension literals?

An example:

... the rest of the file is white.

Doesn't cause a problem when the list is recognized as an error.

For some reason this (erroneous) pattern fixes the highlighting (it then continues as normal).
Note that | ] (with a space) doesn't work.

Also, this works

And this works

Thanks for the bug report, this was a problem with the highlighter for quasiquotations. I've committed a fix to the repository and added a test case.

By the way, I recommend using a different theme, one that supports more of the syntax highlighting scopes provided by this extension. I've put together the colours I'm currently using into a theme on the VS Code Marketplace which you might be interested in trying out. The repository for the theme also contains some info about customising your theme if you want to change anything.

Thanks for the quick fix. I didn't know about quasiquoting at all, looks like an interesting feature of Haskell. Thanks for the theme recommendation too, I went with atom dark instead but highlighting infix operators is a nice idea.
