Summary: @public After reading about move-semantic and rvalue refs I realized that we (I) definitely overuse `auto &&` (aka universal reference) construction. Even if this is harmless, does not look good and idiomatic. Whenever I used that from a semantical point of view I always meant "I need an alias for this" which is actually "read-only reference" which is `const auto &`. This is also fit good to our policy where "everything is const (immutable) by default". Hence I change that to how it should be.
