Re^4: on the fly reference to subroutine output

[tmharish]

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.
