[stdlib] Add Sequence.Element, change ExpressibleByArrayLiteral.Element to ArrayLiteralElement #8990

airspeedswift · 2017-04-25T03:03:30Z

This change will allow generic algorithms to refer to Sequence.Element instead of Sequence.Iterator.Element.

The PR is big but the vast bulk of the changes are removal of Iterator. from numerous lines.

Here is some code that will break if we constrain Sequence.Element == Iterator.Element:

struct S<T>: RandomAccessCollection {
  var _a: [T]
  var startIndex: Int { return _a.startIndex }
  var endIndex: Int { return _a.endIndex }
  // This infers Element == T
  subscript(i: Int) -> T { return _a[i] }
}

extension S: ExpressibleByArrayLiteral {
  // ExpressibleByArrayLiteral has a typealias of Element
  // for the elements of the array literal
  init(arrayLiteral: Any...) {
    _a = arrayLiteral.map { $0 as! T }
  }
}

This PR is changes ExpressibleByArrayLiteral.Element to ArrayLiteralElement. It appears no projects in the combat test suite rely on this (would only be observable if you conformed to ExpressibleByArrayLiteral.Element but not Sequence).

The CSDiag crashers are because the Swift compiler has the name Element hardcoded for this associated type:

There are other issues in the solver, at least one of which is a transform that should probably be some form of substitutions.

The stdlib/NewArray.swift.gyb seems like typechecker-related source breakage consequence of the ArrayLiteralElement change, but it's quite a contrived case (retroactive conformance of an array-like protocol to Swift.Array).
