This was made on C++ level, and repeated in all plugins.

Reason -- speed, less RAM resources, ...

Why spend time and RAM
    to create empty array,
    later to destroy it
    on call of function get_Count() to see that it is empty

?

Instead we have simple

    res = field.find

    if( res = nil )
        return  // or else you want
