I do:

  some_sub([ [1,2,3], [4,5,6] ]);

  sub some_sub {
    my $aref = shift;
    print $aref->[0][0];  # 1
    print $aref->[1][2];  # 6
  }

I suggest you read

  perldoc perlreftut
  perldoc perlref
  perldoc perllol
  perldoc perldsc

Not all *MUST* be read, but the last two are definitely helpful for coming
up with ways of dealing with your structures once you've made them.  The
first two are definitely a good starting place, though.

I also have some documentation I wrote up:
