C++ concepts: StandardLayoutType
Specifies that a type is standard layout type. Standard layout types are useful for communicating with code written in other programming languages.
Note, that the standard doesn't define a named requirement or concept with this name. This is a type category defined by the core language. It is included here as concept only for consistency.
