Warnings of unused imports in GHC-9 #16

Closed s9gf4ult closed 2 years ago

s9gf4ult commented 2 years ago

Since GHC-9.0.2 I see such warnings despite the import is actually used.

<no location info>: warning: [-Wunused-imports]
    The qualified import of ‘GHC.Stack’ is redundant
      except perhaps to import instances from ‘GHC.Stack’
    To import instances alone, use: import GHC.Stack()
