Re: Modifying code generator to support pass by reference values

Generally, I don't like to add any non-standard stuff to .defs files. I've emailed language-bindings list to see whether in/out tag can be added to parameter definitions for next defs version. Then we could easily do this. For now, I'd still say hand-code those, or modify generator temporarily, generate code, and then copy-paste it into .overrides.
