Parsing UnicodeSyntax with haskell-src-exts

Question

I have a Haskell source file which using Unicode syntax:

{-# LANGUAGE UnicodeSyntax #-}
succ\' :: Int → Int
succ\' = succ

main :: IO ()
main = print $ succ\         


        

Answer 1

From a cursory glance at the source, it doesn't look like parseModule extracts language pragmas from the source before parsing (parseFile does do that by calling getExtensions). By the time parsing has begun, it is already too late to enable unicode syntax.
