[Feedback requested]: -fhelpful-import-errors

Hi, I raised a ticket to request a new feature: -fhelpful-import-errors. This flag should enable helpful errors if there are typo's in the internal imports of your projects. As suggested by `thomie`, I created a design proposal at https://ghc.haskell.org/trac/ghc/wiki/Proposal/HelpfulImportError and am now looking for feedback. Thank you for your time. -- Tom Sydney Kerckhove
