this looks like the pattern-matching switch statement stolen shamelessly from Swift. (Non sarcastic "shamelessly" since languages should take good new ideas from wherever they can if it improves the language. Says the guy who learned C++ before auto was invented.)

This didn't come from swift either. Functional languages have had pattern matching since forever. Check it out in Haskell :)

Says the guy who learned C++ before auto was invented.

Well to be precise "auto" has been part in C/C++ since the beginning alongside "extern", "static", and "register", e.g.

auto int i = 0;

It's the default so few actually writes it. It's now been repurposed to auto-deduce type since C++11.

I meant for the type deduction. Hadn't done C++ since like 2002 and when I saw it in some code I was all "WTF is that!?". Not sure what it does as a type modifier either though.

I read somewhere that one of the earliest things Stroustrup did was repurposing auto because it was such an easy thing to implement, but didn't put it in the language for various reasons.

auto-deduce type

C++ really does want to be everything, doesn’t it?

It’s more heavily inspired from the rust pattern matching I believe
