This isn't semantics, though, but implementation. As far as I'm aware there's no way to "observe" the copy short of digging into runtime debugging tools, so I think it's still fair to say the language has pass-by-value semantics. In C++ we still refer to things returned-by-value as returned by value despite the reality of NRVO, etc. |
