Pitch: Multi-statement if/switch/do expressions

[sspringer (Stefan Springer)]

Explicitly disagreeing with other posts calling this variant "hard to read", "not swifty" (oh how I dislike this phrase :D), or "subtle"

That‘s fine, there are different opinions in that.

@ahti

I suspect some of these opinions are affected by thinking about this as a new thing that needs a spotlight shone on it. Imo, we should give more consideration to the long term, where this is would be a normal Swift feature, probably one programmers encounter and learn early on.

I disagree with this, I would value those opinions higher, see e.g. the comments from some people knowing the last line feature from Rust, and many people do like it that we need a “return” when a function body has several statements.

@ahti

A keyword seems to me like it makes people expect return/break/continue-like behaviour, something affecting the flow of execution

Like “return” references the inner closure, “then” or “use” would reference the inner if/switch/do expression, nothing new here so to speak. Some people might want more, and indeed this is less simple, but should not serve as an argument against the simple case.

I did not really understand what follows, but I am comment no. 412. Wow.
