Having worked in Rust I love the pattern matching proposal. Having dabbled in Swift I like the single argument function part (though keep the brackets, please)

Much of the rest I could take or leave… but then is that just because I’m not familiar with them? Stuff like the pipe operator makes sense to me but it reminds me of .reduce(): there are a few legitimate uses of it but the vast majority will be entirely-too-smart—for-its-own-good show off coding.
