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.
