Issue Description:

If I have a [String: Any] I can't subscript this with a Substring without first copying the substring. This is a very obvious case of where the copy shouldn't be necessary (well, assigning to the subscript needs a copy, but the getter shouldn't).

Filing at the request of @milseman.
