+// Mappings and Sequences of descriptors.
+// Used by Descriptor.fields_by_name, EnumDescriptor.values...
+//
+// They avoid the allocation of a full dictionary or a full list: they simply
+// store a pointer to the parent descriptor, use the C++ Descriptor methods (see
+// google/protobuf/descriptor.h) to retrieve other descriptors, and create
+// Python objects on the fly.
+//
+// The containers fully conform to abc.Mapping and abc.Sequence, and behave just
+// like read-only dictionaries and lists.
+//
+// Because the interface of C++ Descriptors is quite regular, this file actually
+// defines only three types, the exact behavior of a container is controlled by
+// a DescriptorContainerDef structure, which contains functions that uses the
+// public Descriptor API.
+//
+// Note: This DescriptorContainerDef is similar to the "virtual methods table"
+// that a C++ compiler generates for a class. We have to make it explicit
+// because the Python API is based on C, and does not play well with C++
+// inheritance.
