Can't use identifiers from loaded modules

[brandon-leapyear]

Minimal repro:

1. Write a file Foo.hs like

   module Foo where
   
   x :: Int
   x = 1
   

2. Run stack ghci --package hint, then in the shell, do:

   import qualified Language.Haskell.Interpreter.Hint
   import Control.Monad.IO.Class
   Hint.runInterpreter $ do { Hint.loadModules ["Foo.hs"]; liftIO . print =<< Hint.getModuleExports "Foo"; Hint.eval "x" }
   

The output I see is:

[Fun "x"]
Left (WontCompile [GhcError {errMsg = "<interactive>:3:1: error: Variable not in scope: x"}])

which shows that x was loaded, but evaluating it doesn't work. Same thing happens with other functions like typeOf

:sparkles: This is an old work account. Please reference @brandonchinn178 for all future communication :sparkles:

Ah I guess I have to do

loadModules ["Foo.hs"]
setTopLevelModules ["Foo"]
eval "x"

is that intended? If so, the docs could clarify what the difference between loadModules and setTopLevelModules intends

I have clarified the behaviour of loadModules in the documentation, which will be updated in the next release.
