Hi ghc-devs, About 10 days ago, I made a thread about defining a function called elaborateExpr which turns a string into a core expression https://github.com/yiyunliu/ghc-elaboration-test/blob/8f362ad92dc6601b4cb7e4... within an interactive context. Now here's an unexpected behavior which I'm not sure how to deal with. Given the expression: (\x -> x + 1) :: Int -> Int I expect to get something that looks like: \ (x :: Int) -> + @ Int GHC.Num.$fNumInt x (GHC.Types.I# 1#) where GHC.Num.$fNumInt is the exported dictionary. What I actually get is something like this: \ (x :: Int) -> + @ Int $dNum_someuniqueid x (GHC.Types.I# 1#) where $dNum_someuniqueid is a free dictionary variable within the expression. I was confused by the occurrence of the free variable $dNum at first, but after running the command: "ghc -ddump-ds-preopt somefile.hs" to dump the core bindings, I found that the dictionary variables like $dNum_ are actually local variables defined at the top-level. My objective is to inline those top-level dictionary definitions into the core expression using let bindings, but it seems tricky since I'm doing everything within an interactive context. Calling getBindings https://hackage.haskell.org/package/ghc-8.6.5/docs/GHC.html#v:getBindings only gives me the expression I elaborated, but the dictionary is no where to be found. Interestingly, when I turn on flags such as "DeferTypedHoles" or "DeferOutOfScopeVariables", all the dictionaries are defined locally in let bindings. However, I can't replicate that behavior even with the flags on in the interactive context. How do I find the dictionaries? Thanks, - Yiyun
