Error parsing '(,)

[basile-henry]

The following program is valid (using template-haskell):

{-# LANGUAGE TemplateHaskell #-}

import Language.Haskell.TH.Syntax

main = print $ showName '(,)

However stylish-haskell doesn't parse it properly:

stylish-haskell git:(master) 
➜ git rev-parse HEAD        
d24532c82472c4d11947a0afe8941f930664b0ac

stylish-haskell git:(master) 
➜ stack exec -- stylish-haskell --version
stylish-haskell 0.9.0.2

stylish-haskell git:(master) 
➜ stack exec -- stylish-haskell /path/to/Test.hs
Language.Haskell.Stylish.Parse.parseModule: could not parse /path/to/Test.hs: ParseFailed (SrcLoc "<unknown>.hs" 5 27) "Parse error: ,"

@wdanilo If you need a workaround, you can define pair = (,) in one module and then use 'pair in another (TH staging restrictions). Hope this helps 😃
