Bug or just something you can't do ?

[Alex Tweedly]

This very simple script doesn't work. Question is whether it should or not ?

Intutively, to me, it should work. The element of the array can be 
treated just like a simple variable - use its value, assign to it, etc. 
-  but it cannot be used as the actual parameter to a pass-by-reference 
parameter.

I can't find anywhere in the documentation that says that - but I can't 
actually find anywhere that it would say that - the docs I've found are 
pretty quiet on the subject of what an array is, or what an element is.

Is this a deficiency you would expect ?
Or should I submit as a bug/request ?

Thanks
