in thread on the fly reference to subroutine output

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

    sub 2 now gets the ref of the outer anonymous array which is flattened.
