The thin arrow in Swift is used to define to result type of a function /
closure.
someFuncWithClosure { (a: Int, b: Int) -> String in "\($0 + $1)" }
Am I understanding this correctly that
your first suggestion is
someFuncWithClosure { (a: Int, b: Int) -> String => "\($0 + $1)" }
and your second suggestion is
someFuncWithClosure { (a: Int, b: Int) => String in "\($0 + $1)" }
?
C# doesn't allow specifying the return type for closures (you have to define a
delegate type first)
someFuncWithClosure((int a, int b) => string.Format("{0}", a + b));

In wanted to propose either adding the fat arrow (=>), or replacing the thin
arrow with the fat arrow.
I know that Java uses the thin arrow, but JavaScript, TypeScript and C# both
allow the use of the fat arrow for lambda syntax.
Thoughts?
Thanks,
