> In general, we have the collection of protobuf messages as another protobuf message, which makes JSON -> protobuf conversion straightforward. This is not always the case, for example, {{Resources}} class is not a protobuf, though protobuf-convertible.
> To facilitate conversions like JSON -> {{Resources}} and avoid writing code for each particular case, we propose to introduce {{JSON::Array}} -> {{repeated protobuf}} conversion. With this in place, {{JSON::Array}} -> {{Resources}} boils down to {{JSON::Array}} -> {{repeated Resource}} -> (extra c-tor call) -> {{Resources}}.
