Simple Example

let

  y = "i";
  z = "s";
in
  x + y + z

Did you check whether the Haskell lexer works good enough?

In any case, we are currently using Scintillua for syntax highlighting. Please fill an upstream issue.

I think the haskell lexer can mostly work. I haven't checked yet but will soon.

I think the haskell lexer can definitely mostly work for PureScript.
