Parse error on import {-# SOURCE #-} #2

Using build system Stack

pstateSourcePos = SourcePos {sourceName = "./src/AppEnv/Types.hs", sourceLine = Pos 1, sourceCol
umn = Pos 1}, pstateTabWidth = Pos 8, pstateLinePrefix = ""}})

Seeing the above error running prune-juice.exe on a stack based project in WSL on Windows 10. Looks like it doesn't handle importing .hs-boot files?

@dfithian thanks just tested with that commit, there's no longer a parse error
