Single-element parethesized expressions/tuples vs common use of parentheses
parentheses, swift, tuples
Solution
From Types in the Swift book:
If there is only one element inside the parentheses, the type is simply the type of that element. For example, the type of `(Int)` is `Int`, not `(Int)`.
So the type of `(2)` or `(2+4)` is simply `Int`, and the `*` in `(2+4)*5` is just integer multiplication.
Problem
Sorry if this is trivial - I am so new to swift, actually I have only looked at the language guide+reference for a few minutes. As far as I understand a parenthesized expression like `(2,3)` is used to construct a tuple, and `(2)` is a single-element tuple of type `(Int)`. But then what happens with common use of parentheses like `(2+4)` in expression `(2+4)*5`? Is this still a tuple of type `(Int)` multiplied by an `Int`?
