Accepted proposals which do not have a complete implementation
This is the list of proposals which have been accepted for inclusion into Swift, but they are not implemented yet, and may not have anyone signed up to implement them. If they are not implemented in time for Swift 3, they will roll into a subsequent release.

- SE-0042: Flattening the function type of unapplied method references
- SE-0045: Add scan, prefix(while:), drop(while:), and iterate to the stdlib
- SE-0047: Defaulting non-Void functions so they warn on unused results
- SE-0048: Generic Type Aliases
- SE-0052: Change IteratorType post-nil guarantee
- SE-0060: Enforcing order of defaulted parameters
- SE-0063: SwiftPM System Module Search Paths
- SE-0066: Standardize function type argument syntax to require parentheses
- SE-0067: Enhanced Floating Point Protocols
- SE-0068: Expanding Swift
Selfto class members and value types - SE-0075: Adding a Build Configuration Import Test
- SE-0076: Add overrides taking an UnsafePointer source to non-destructive copying methods on UnsafeMutablePointer
- SE-0080: Failable Numeric Conversion Initializers
- SE-0081: Move
whereclause to end of declaration - SE-0082: Package Manager Editable Packages
- SE-0088: Modernize libdispatch for Swift 3 naming conventions
