You should've noticed three things before writing it: 1) His background is C++/Embedded. 2) He does that successfully for a living. 3) He really knows what he's talking about.

The parent is right about the copy elision part (http://en.wikipedia.org/wiki/Return_value_optimization). GCC definitely performs this and I'm sure that it's true of other widely used C++ compilers.

I also don't know what yosefk means when he says that smart pointers rely on defective meta-programming techniques. The implementation of Boost's smart_ptr doesn't seem too esoteric to me.

So is this how "appeal to authority" works in language pissing contests? The "authority" is money? "I make money using this language so blah blah blah QED."

No, this is how refutations to "he doesn't know anything" work.
