[Joachim Breitner]

Hi,

Thanks! I’ll update the tally later today.

That is my sentiment as well, and I would phrase my vote as:

  GHC2021 implies UnicodeSyntax, but not -fprint-unicode-syntax.
  Enabling UnicodeSyntax explicitly may still imply -fprint-unicode-syntax.

I guess the details of how GHC formats its messages are not strictly
our authority, so I didn't spell this out, but yes: it helps to paint
the picture here more clearly.

Interesting, I don’t see a mention of this on
https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/glasgow_exts.html#extension-InstanceSigs
Can you elaborate?


Also thanks for looking up which extensions are already in GHC,
Haskell2010 and are deprecated. I should indicate that in the table
somehow (or simply drop them from the ballot, at least the deprecated
ones).

Cheers,
Joachim
