in thread element of an array of arrays

So when I push arrays onto an empty array, that doesn't create an array of arrays ?

Interesting, that's not where I thought the problem was. Now I'm at a loss. How would I create an array of arrays with that data ?

    I just updated my answer w/ code that creates an AoA. You were basically pushing a list into an array and it gets incorporated into the array just like all the elements. What you needed to do was push an array reference.

    an array of arrays is an array of arrayrefs

    When you push @arra, @array you're pushing a list onto @arra

    push @arra, \@array; ## pushing arrayreference, array of arrays achieved

      perldoc -f push
      push ARRAY,LIST
      push EXPR,LIST
      Treats ARRAY as a stack by appending the values of LIST to the end of ARRAY. The length of ARRAY increases by the length of LIST.
