Champions Meeting 2024-09-06

Attendees: Tab, Ron, Jordan

• Waldemar says no new contextual infix keywords, suggests ~= instead of is

  • Syntax effects on rest of the language #323
  • https://github.com/waldemarhorwat/syntax/blob/main/contextual-keywords.md
  • We'll leave it alone for now, mark it explicitly as a thing to solve before Stage 2

• Visibility of the pattern cache to if() bindings

  • How do if(<expression>) guard patterns interact with array/object pattern caches? #321
  • Jordan's initial intuition said it was cached, but we all agree it can't be, that's arbitrary JS space

• Regex patterns - it seems like this is the one that trips people up wrt complexity. I'd be sad about losing the regex literal syntax, but I could accept it for now, as long as the regex custom matcher remains.

  • Ron says yes, drop it.
  • Jordan is fine as long as the custom matcher remains.

• Discard patterns

  • committee was split on _ vs void
  • Ron wants to just go with void, duplicate _ stuff has inconsistencies/issues
  • we'll currently stick with void in pattern matching, mark it as an "addition in line with concurrent proposals"

• Tab will make README changes and prep slides Soon

  • Another champion meeting to go over the slides before plenary
  • Jordan is volunteering to do the plenary presentation, I think? (Tab won't be there, conflicting multi-day meeting.)

Happy to do the presentation as long as we've had a chance to do a runthrough in advance :-)
