[racket-users] Creating truly unique instances of structure types?

To my knowledge, there are two main techniques for creating unique values in Racket: `gensym` and structure type generativity. The former seems to be bulletproof — a value created with `gensym` will never be `equal?` to anything except itself – but the latter isn’t. Using reflective operations,

[racket-users] RacketCon 2018 videos

Hello, I noticed that Youtube has a few streams of the recent RacketCon event. I can get the gist of what the speakers are saying, but they are hard to follow in detail. Any word if higher quality uploads are available for the talks? I don't know who to thank for all of the previous years' rec
