Look here:
https://gitlab.haskell.org/ghc/ghc/merge_requests/444/diffs#350c4076427c611b8f14e875a4ca553041c2b847_1930_1925
Look at the comment “Is this zipping necessary? We haven't zonked the scoped_kvs or the tc_tvs, I think” from Richard Eisenberg, just below line 1925 in TcHsType.
Now click on the grey “…” above his comment, to expand more code lines above.
Uh oh!
- The same comment now occurs twice, just below line 1904, and again just below 1925.
- The first time it’s on the wrong line of code
- But in the second position (the correct one) the “Reply” box is inactive. I can’t type into it.
Is this is a bug? How to report it?
