If we were to create a Rust version of this page for Haskell, what cool programming techniques would you add to it?

Rust isn't really a language that lends itself to terse point-free functional idioms... The sort of examples I might want to share would probably require a bit more context, certainly more code. Like I think type guards and arena allocation are cool and useful tricks but I don't think I could write a neat little example showing or motivating either

Yeah I don't mean just terse functional idioms. Any programming technique that blew your mind the first time you came across it would qualify.

Type guards, then :) very cool, much compiler power, love it

Maybe they're referring to "where clauses"?

Indeed I am. Forgot the name, lol, not worked with rust for a few months 😅
