 Could you bring a practical example of where this is a problem?


I had a program that'd make many recursive function calls.  When done at each
level, it'd add to an associative array and then return.  Creating an AA and
passing it into a function does not work, because an empty AA is null. 
Wrapping in another object or using a pointer the the array was needed to fix
the issue.
