alt Hacker NewsAuto has really made c++ unapproachable to me. It's hard enough to reason about anything templated, and now I frequently see code where every method returns auto. How is any one supposed to do a code review without loading the patch into their IDE?

The pain of lisp without any of the joy.

Same in Java and Kotlin, but then again, the majority of people who write code wouldn't understand what I mean when I say "whether a collection is returned as List or Set is an important part of the API 'contract'".
I'd suppose this really depends on how you are developing your codebase but most code should probably be using a trailing return type or using an auto (or template) return type with a concept/requires constraint on the return type.
For any seriously templated or metaprogrammed code nowadays a concept/requires is going to make it a lot more obvious what your code is actually doing and give you actually useful errors in the event someone is misusing your code.
