Fellow monasterians,

I'm practicing building an AoHoAoH so I can do nested loops in HTML::Template. Though I don't really need to know this for the purposes of H::T, I was curious how to access this data structure:

my @AoH=( { chapter => "Basic",              
            page  => (
                       { paragraph => "lesson1"},
                       { paragraph => "lesson2"}
                     ) 
          },
          { chapter => "Advanced",
            page  => (
                       { paragraph => "lesson3"},
                       { paragraph => "lesson4"}
                     ) 
          }
        );

Tried:

print $AoH[1]{page}{paragraph};

printed: lesson3

But in an attempt to get "lesson4" to print:

print $AoH[1]{page}[1]{paragraph};

printed: not an ARRAY reference

Two questions: 1) is this truly an AoHoAoH? 2) how do I access that 2nd element of the 2nd element? Thank you!
