I don't like where this is heading.
If you want to introduce method cascading, then have a look at Dart.
E.g. the example from the pull request could be something like this:
let questionLabel = UILabel()
..textAlignment = .Center
..font = UIFont(name: "DnealianManuscript", size: 72)
..text = questionText
The expression could still work on a mutable struct/class which later
becomes
immutable by using the `let` assignment.
The other example which silently creates a new instance is even worse.
If you want to do something like this, then please do it more
explicitly.
E.g.:
let fewerFoos = foos.clone()
..remove(at: i)
Anyway, all of this is simply syntactic sugar and should wait...
