C++11 lambda functions capture variables declared in their outer scope by value-copy or by reference. This means that value members of a lambda cannot be move-only types. [13] C++14 allows captured members to be initialized with arbitrary expressions. This allows both capture by value-move and declaring arbitrary members of the lambda, without ...
The rules are effectively the same as inline functions __has_include, allowing the availability of a header to be checked by preprocessor directives [25] Value of __cplusplus changed to 201703L [26] Exception specifications were made part of the function type [27] Lambda expressions can capture "*this" by value [28]
The lambda lift is the substitution of the lambda abstraction S for a function application, along with the addition of a definition for the function. l a m b d a - l i f t [ S , L ] ≡ let V : d e - l a m b d a [ G = S ] in L [ S := G ] {\displaystyle \operatorname {lambda-lift} [S,L]\equiv \operatorname {let} V:\operatorname ...
concepts (what made it into the standard is a cut-down version; also described as "Concepts Lite" [85]) designated initializers [=, this] as a lambda capture; template parameter lists on lambdas; std::make_shared and std::allocate_shared for arrays; Changes applied to the C++20 working draft in the fall meeting in November 2017 (Albuquerque ...

In such a case, a common solution is to create a clone (or similar) virtual function that creates and returns a copy of the derived class when called. A member function can also be made "pure virtual" by appending it with = 0 after the closing parenthesis and before the semicolon. A class containing a pure virtual function is called an abstract ...
