How does 'flattening' come into play when there's only one array? I would think 'unwiding' of an array is what takes place.

There are two arrays ( one inside the other ). The outer array is the anonymous array as shown below: `sub2( [ sub1() ] ); ^ ^ \| \| \| --------- Inner array ------------ Outer array` [download] sub 2 now gets the ref of the outer anonymous array which is flattened.	[reply] [d/l]
