/**
* array_merge_recursive does indeed merge arrays, but it converts values with duplicate
* keys to arrays rather than overwriting the value in the first array with the duplicate
* value in the second array, as array_merge does. I.e., with array_merge_recursive,
* this happens (documented behavior):
*
* array_merge_recursive(array('key' => 'org value'), array('key' => 'new value'));
* => array('key' => array('org value', 'new value'));
*
* array_merge_recursive_distinct does not change the datatypes of the values in the arrays.
* Matching keys' values in the second array overwrite those in the first array, as is the
* case with array_merge, i.e.:
*
* array_merge_recursive_distinct(array('key' => 'org value'), array('key' => 'new value'));
* => array('key' => array('new value'));
*
* Parameters are passed by reference, though only for performance reasons. They're not
* altered by this function.

* In the OpenLSS version array_merge_recursive_distinct is renamed to mda_merge
* Also there is now a variable amount of merge variables
* References have been removed to prevent unpredictable results and to support variable
* argument lists.
