Gregory's Serverequal-always? in Racket 8.6 is maybe the first interesting equality predicate anyone has added to any programming language in a while, and a surprising justification to add something new to the existing pile of eq?/eqv?/equal? https://docs.racket-lang.org/reference/Equality.html#%28def._%28%28quote._~23~25kernel%29._equal-always~3f%29%29

 @craigmaloney @cwebber Yeah, I'm pretty invested in Racket the scheme-like-thing for teaching, but I guess there are plenty of schemes that will work. Christine's tutorial which works in Racket or Guile is basically a compressed version of the second course where I use Racket.  @cwebber My mind has been blown. This is not something I would have ever thought about, yet it seems like something that is so obvious in retrospect.  |
@cwebber Racket is doing such interesting things with Scheme. This is why I hope they don't ruin it with their variant on trying to remove parens and make more like Python. I think that's a Perl6-level mistake in the making.
