:mrdocs:

Invoke the specified `accessor` on the non‐modifiable value stored in the specified "nullable" `object`. The supplied `accessor` must be a callable type that can be called as if it had the following signature: ` int accessor(const VALUE_TYPE& value); ` Return the value from the invocation of `accessor`. The behavior is undefined unless `object` does not contain a null value.
