Hmmm... allow me to take a shot at this.

how about...

$myArray[$#myArray][$#{$myArray[$#myArray]}][$#{$myArray[$#{$myArray[$#myArray]}
]}]

which looks like...
		$myArray[$#myArray]
	    [$#{$myArray[$#myArray]}]
[$#{$myArray[$#{$myArray[$#myArray]}]}]

if you line up the sqare brackets.

:)

why?  as far as I know, $myArray[ somenumber ] refers to an array reference,
and $myArray[ somenumber ][ anothernumber] is another array reference.  And
$myArray[ somenumber ][ anothernumber ][ whenisthisgonnaend ] is a scalar.
So I'll refer to the last indexed value of the array reference.

Knowing the above, you can probably predict the results of this code snippet.

===== code snippet =====
@thisray = (
   [0, 1, 2],
   [a, b, c, d],
   [0, 1, 2, 3, 4, 5]
   );

print $#thisray, "\n";
print $#{$thisray[0]}, "\n";
print $#{$thisray[1]}, "\n";
print $#{$thisray[2]}, "\n";
===== end code snippet =====
