### Move semantics and temporary values {#TemporaryValues}
Sometimes, it is convenient to construct a Value in place, before passing it to one of the "moving" functions, like `PushBack()` or `AddMember()`. As temporary objects can't be converted to proper Value references, the convenience function `Move()` is available:
~~~~~~~~~~cpp
Value a(kArrayType);
// a.PushBack(Value(42)); // will not compile
a.PushBack(Value().SetInt(42)); // fluent API
a.PushBack(Value(42).Move()); // same as above
