@idontgetit holds the two array refs. @idontgetit->[0] indexes the first one of it, and the second ->[0] indexes the first element of the (inner) array.

BTW, @idontgetit->[0]->[0] should better be written as $idontgetit[0]->[0] (turn on warnings, and Perl will tell you why).

I saw that warning before (I try to crack these nuts for a few hours before I ask the monks). I failed with `$idontgetit->[0]->[0]` and just went back to the `@` syntax since it printed anything. Sometimes Perl forgives my syntax, sometimes not.	[reply] [d/l] [select]
