Detailed Description

Variable binding target runtime.

VariableBindingTargetRuntime holds the result of a binding operation as a readable variable.

VariableBindingTargetRuntime is intended to be used with a specific lookup in a binding host that is not a PropertyObject. This enables storing binding results without the overhead of PropertyObject interface.

There is no base value to modify, so VariableBindingTarget cannot write into a property field.
