{{{
{-# LANGUAGE TemplateHaskell #-}
module MkData where
import Language.Haskell.TH
import Language.Haskell.TH.Syntax
op a b = a + b
decl = [d| func = 0 `op` 3 |]
}}}
Works with 6.8.3, but with the 6.10 beta, it dies with the strange message
{{{
C:\Users\JCAB\Haskell\THTest>ghc --make main.hs
[1 of 2] Compiling MkData ( MkData.hs, MkData.o )
attempting to use module `main:MkData' (.\MkData.hs) which is not loaded
}}}
When looking up `op`, GHC doesn't find the fixity correctly. (SLPJ
comment: having looked at the code in `RnEnv.lookupFixity` I can't see how
6.8.3 works!)
