Hi everyone,
We received a pull request in swift-corelibs-foundation which is
apparently in response to a language change for SE-0110.
It turns this perfectly reasonable code:
- self.forEach { (keyItem, valueItem) in
into this:
+ self.forEach { (arg) in
+ let (keyItem, valueItem) = arg
Is that really the design pattern we want to encourage? What was wrong
with the previous code?

I'm no language designer, nor an compiler engineer. However we should
definitely be able to use the former expression as it has better
readability over the latter IMO.
