•Created with the Alt D shortcut key in a variable. This is a data type that can act as both an allocator and a reference.
•If a reference is assigned, it is treated as a reference.
•When an allocator or constructor is assigned, it is treated as an allocator and clear the existing allocator. In this state, if the mixed reference variable is deleted or points to another variable, the variable originally pointed to is freed.
•When assigning an allocator or other hybrid reference to a hybrid reference, you can use the Alt P shortcut key to assign the reference.
