I made a version for the syntax bee. https://github.com/bennn/syntax-parse-example/pull/26/files

Use (require "dot-underscore.rkt") to try it.

properties can be methods? (I know they can be coded that way, it’s just I think of them more as fields, something known about an object, not something that could change on every call/access.)

OTOH, when I was younger, my height property was 5′7", and now it seems to be more like 5′6–1/2".
