:mrdocs:

Invoke the specified `accessor` on the non‐modifiable element at the specified `index` of the specified `array`. The supplied `accessor` must be a callable type that can be called as if it had the following signature: ` int accessor(const ELEMENT_TYPE& element); ` Return the value from the invocation of `accessor`. The behavior is undefined unless `0 <= index` and `index < size(array)`.
