Скотт Майерс выложил предварительное содержание будущей книги Effective C++11. Мне нравится, по большому счету, чтение самого содержания + немного размышлений довольно хорошо помогает понять C++11.

Moving from C++98 to C++11

• Prefer auto to explicit type declarations.
• Remember that auto + { expr } ⇒ std::initializer_list.
• Prefer nullptr to 0 and NULL.
• Prefer enum classes to enums.
• Prefer alias templates to typedefs.
• Declare overriding functions override.
• Distinguish () and {} when creating objects.
• Prefer emplacement to insertion.
• Declare functions noexcept whenever possible.
• Make const member functions thread-safe.
• Avoid std::enable_if in function signatures.
• Handle iterators where copying means moving.

Rvalue References, Move Semantics, and Perfect Forwarding

• Distinguish universal references from rvalue references.
• Avoid overloading on universal references.
• Pass and return rvalue references via std::move, universal references via std::forward.
• Assume that move operations are not present, not cheap, and not used.
• Be aware of perfect forwarding failure cases.
• Understand reference collapsing.

Secrets of the C++11 Threading API

• Thread construction may throw.
• Destroying a joinable thread calls terminate.
• Arguments passed to std::thread, std::async, and std::call_once are unconditionally copied.
• std::async is really two different functions with somewhat different APIs.
• Futures from std::async are special.
• void futures can be used for interthread communication.
• To poll a future, use wait_for with a zero timeout.
• Native handles let you go beyond the C++11 API.
• Clock adjustments affect _until functions.

Lambda Expressions

• Prefer lambdas to std::bind.
• Prefer lambdas to variadic arguments for threading functions
• Beware default captures in member functions.

Smart Pointers

• Use std::make_shared whenever possible.
• Prefer pass-by-ref-to-const to pass-by-value for std::shared_ptrs.

Miscellaneous

• Pass by value when you’ll copy your parameter.
• Keep abreast of standardization developments.
