* Nest various top-level Iterator and Index types, and flatten extensions.
* Fix tests from nesting iterator
* Nest Unsafe*BufferPointer.Iterator, extensionify UnsafeBufferPointer
* Degyb LazyCollection
* Nest Flatten iterator and index
* Eradicate IndexDistance associated type, replacing with Int everywhere
* Consistently use Int for ExistentialCollection’s IndexDistance type.
* Fix test for IndexDistance removal
* Remove a handful of no-longer-needed explicit types
* Add compatibility shims for non-Int index distances
* Test compatibility shim
* Move IndexDistance typealias into the Collection protocol
* Refactor Indices and Slice to use conditional conformance
* Replace ReversedRandomAccessCollection with a conditional extension
* Refactor some types into struct+extensions
* Revise Slice documentation
* Fix test cases for adoption of conditional conformances.
* [RangeReplaceableCollection] Eliminate unnecessary slicing subscript operator.
* Add -enable-experimental-conditional-conformances to test.
* Gruesome workaround for crasher in MutableSlice tests
Introduce (recursive) constraints that make the *Collection constraint
of SubSequence match that of its enclosing *Collection, e.g.,
MutableCollection.SubSequence conforms to MutableCollection.
Fixes rdar://problem/20715031 and more of SR-3453.
* Give Sequence a top-level Element, constrain Iterator to match
* Remove many instances of Iterator.
* Fixed various hard-coded tests
* XFAIL a few tests that need further investigation
* Change assoc type for arrayLiteralConvertible
* Mop up remaining "better expressed as a where clause" warnings
* Fix UnicodeDecoders prototype test
* Fix UIntBuffer
* Fix hard-coded Element identifier in CSDiag
* Fix up more tests
* Account for flatMap changes
* removing .characters from examples
* beginning new String doc revisions
* improvements to the String Foundation overlay docs
* minor revisions elsewhere
Added tests for expected-error and fix-its.
- Add arguments signature regardless that is the same as before.
Because the error message looks more natural.
e.g. "makeIterator" => "makeIterator()",
"replaceSubrange" => "replaceSubrange(_:with:)"
- Any${ExistentialCollection}.underestimateCount() was a method, not
computed property.
- 'LazySequenceType' has been renamed to 'LazySequenceProtocol', but not
'LazyCollectionProtocol'
- Streamable.writeTo(_:) had no argument label.
- Fixed typo in print() debugPrint() error message (not working for now)
- Repeated.init(): changed `renamed` to `message` because the arugment
order has changed.
- Marked `public` for some unavailable method on `Sequence`
- Sequence.split(_:maxSplit:allowEmptySlices) was replaced with
split(separator:maxSplits:omittingEmptySubsequences:),
not split(separator:omittingEmptySubsequences:isSeparator:)
- Sequence.split(_:allowEmptySlices:isSeparator) was replaced with
split(maxSplits:omittingEmptySubsequences:isSeparator:),
not split(_:omittingEmptySubsequences:isSeparator:)
- Sequence.startsWith(_:isEquivalent:) or startsWith(_:) had no label on
the first argument.
- transcode(_:_:_:_:stopOnError), not transcode(_:_:_:_:stoppingOnError)
- Removed mutating methods from UnsafePointer.
alloc(_:), dealloc(_:), setter:memory, initialize(_:), destroy(),
and destroy(_:)
