Misleading error message when quasiquoter not in scope

t.hs:

{-# LANGUAGE QuasiQuotes #-}
main = [$notDefinedHere| |]

ghc's output:

t.hs:2:7: Not in scope: `notDefinedHere'

t.hs:2:7:
    GHC stage restriction: notDefinedHere
      is used in a quasiquote, and must be imported, not defined locally
Failed, modules loaded: none.

The second message is wrong, since notDefinedHere isn't defined anywhere.
