One thing I wish was available in all languages is the ability to return

In languages with dynamic associative arrays (such as PHP), I simulate

Yes. It's conceptually not a parameter. It's a result status that determines
if the result returned is valid. Returning multiple values is also a lot
cleaner and much more generic than having to add a parameter for each out
value to be returned.
