add test for "sync" semantic.
add tests to assure the objects in collections remain the same (object_id).
no longer support instance: {nil}. the lambda can instead access the property itself as it knows the getter and gets the index passed in. this simplifies the code spectacularly.
remove old comments.
move tests to ParseStrategyTest.
move ReadableWriteable out of feature/.
move namespaces for ReadableWriteable.
remove Deprecations.
started working on ParseStrategy.
