This PR adds the Unicode characters
… ⁝ ⋮ ⋱ ⋰ ⋯as binary operators with the same precedence as:and... (Fixes #24269.) Breaking because⋮ ⋱ ⋰ ⋯were formerly parsed as identifiers.It also changes
≔ ⩴ ≕from comparison precedence to assignment precedence, since colon-equals is an assignment by convention (and we already parse:=with assignment precedence). Also breaking.I doubt that this affects any extant code.
In the future, we may want to also accept
⫶(U+2af6) and/or︙(U+fe19) as synonyms for⁝(U+205d) or⋮(U+22ee), but #25157 needs to be fixed before we can canonicalize operators. That won't be a breaking change since⫶ ︙are not currently valid in identifiers.
