# Type.Ref

Creates a Ref type.

## Example

Example usage is shown below.

    const T = Type.Ref('A')                             // const T = {
                                                        //   $ref: 'A'
                                                        // }

    type T = Static<typeof T>                           // type T = unknown

## Guard

Use the IsRef function to guard values of this type.

    Type.IsRef(value)                                   // value is TRef
