but if I want to get it through the reference I have to do

That should be:

but if I want to use the array that $array refrences I have to do

Sorry, I changed the example slightly and didnt change that line.

Anyway, the point to keep in mind that

   $_=[];  # $_ now is a refrence to empty array (anonymous array)
   $_[0]=[];  # the zeroth element of the array @_
   $_->[0]=[];# the zeroth element of the anonymous array
   $_{0}=[];  # the value associated with 0 in %_
   $_{0}->[0]; # element zero in ^^^^^^^^
   $_[0]->[0]; #zeroth element in array refrenced by the zeroth elemtn
+ of @_
   $_->[0][0]={}; #dont need a second ->
   $_->{0}[0]={}; #this works too
   $_->[0]->[0]->{0}="but we can use -> if we want";
   $_->{0}[0]{0}="This is getting confusing";

I dont think %_ is used that much, but I could be wrong.
