One quibble with the details, though: ``` useType([Int]) // Passes Array<Int> useArray([Int]) // Passes an array, containing Int ``` This seems a little magical; by contrast, [Int.self] vs. [Int].self is unambiguous. Moreover (not that I can conceive of a use for it), wouldn't things get hairy if one tries to express `[[Int].self]`? I'd like to propose an alternative: Python has a trailing comma rule for tuples. That is, to distinguish a parenthesized expression from a single-item tuple, the latter must be written as `(item,)`. Perhaps the same idea could be used in this case. That is: ``` [Int] // Array<Int> [Int,] // an array, containing one element Int ``` * Is the problem being addressed significant enough to warrant a > change to Swift? > * Does this proposal fit well with the feel and direction of Swift? > * If you have used other languages or libraries with a similar > feature, how do you feel that this proposal compares to those? > * How much effort did you put into your review?
