> The proposal is to make the new {{cpp.ref}} annotation introduced with THRIFT-2421 language agnostic instead of a C++ specialty only. 
> The annotation changes inlined nested structs into pointers to structs. This behaviour is potentially relevant with all languages using value semantics for nested structs etc.
