I'm very happy to see all the work you're putting into the record discussion, but I'm struggling to see why people are fighting so hard to get the dot character in particular for field access. It seems like a huge amount of work and discussion for a tiny bit of syntactic convenience that we've only come to expect because of exposure to other very different languages.
Is there some fundamental reason we couldn't settle for something like # (a valid operator, but we've already shown we're willing to throw that away in the MagicHash extension) or @ (only allowed in patterns for now)? Or we could even keep (#) as a valid operator and just have it mean category/lens composition.
