Hi everyone, With the sunny days back in this hemisphere, so do the documentation MRs. I have two primtypes for which I'd like some help / review / interesting information: * ByteArray#: This is mostly done, you can observe the current rendered draft documentation here: https://gitlab.haskell.org/ghc/ghc/-/merge_requests/8067#note_425560    Please note that the free-floating "Byte Arrays" section of documentation cannot be exported or re-exported by GHC.Exts, so we're pretty much left with what's in the types' documentation; * Array#:  The ticket is here: https://gitlab.haskell.org/ghc/ghc/-/issues/21462    State of things: In terms of documentation, we have no documentation. Some stuff can be inferred from the SmallArray# haddocks but I doubt that every property / interesting usage / pitfall can be reasonable derived from putting ¬ at the beginning of the SmallArray# documentation. Now, on an unrelated note, I'm also wondering about the fate of GHC.Pack, for a number of reasons. You will find the ticket here: https://gitlab.haskell.org/ghc/ghc/-/issues/21461. My thanks to everyone who's helped me so far, with a special mention to bodigrim and koz ross. Cheers -- Hécate ✨ 🐦: @TechnoEmpress IRC: Hecate WWW: https://glitchbra.in RUN: BSD
