This is a failed attempt at muddying the waters. You don't know what move semantics is? You go learn what they are. Best/simplest way is to just disable your copy ctor.

You need to know the operator overload semantics for a particular use case? It is not exactly hidden lore, there are even man pages (libstdc++-doc, man 3 std::ostream) or just use std::println.

You are stuck instantiating std::vector? Then you will be stuck in any language anyway.
