Comment (by flip101):

 sgraf do you know where i can see this bug current status? When i search
 on this page i don't find "fixed" apart from your comment. What would be
 interesting is to test all the test cases (found in related bugs) with the
 last version of GHC 8.4.*

 I think this Panic is very helpful. It could be further improved to give
 some tips on how the code can be rewritten to have it compiled correctly.
