 #) Fields in the generated structs are ordered by the tag number, instead of the natural ordering in .proto file.
 #) Unknown fields are not preserved when decoding and re-encoding a message.
 #) Reflection (runtime introspection) is not supported. E.g. you can't request a field by giving its name in a string.
-#) Numeric arrays are always encoded as packed, even if not marked as packed in .proto. This causes incompatibility with decoders that do not support packed format.
