What’s New in Swift 5.2

I understand the difference in difficulty, my point is any incremental time spent on this is wasted and could have contributed towards something else that's useful.

That's not how software development works.

If I've got a new team member, I'm not going to put him on async/await. I'm going to find him something simpler to work on.

Or maybe I've been working on a feature for a few months and I need a break to clear my head so I'll work on a smaller feature for a while.

Software development isn't just assembling widgets on an assembly line. It's a creative process. Developers aren't chained to their desks pumping out a non-descript streams of "code" that become different features. Likely incremental time spent on this had almost no real impact on more difficult and useful features.

Sure, but why should this non-feature which makes code harder to read and reason about even be built in the first place? All to save `.parse` at the call site of a parser, for example?

This syntax already exists in the language. If you want users to be able to use the obj() syntax you can already give them a closure for obj. Allowing it for user-defined types too removes an artificial syntactic distinction.
