Hashes use {}, arrays use [], lists use ().

When you set an element of a hash, you use {} to surround its key:

   $hash{$key} = $value;

When you set an element of an array, you use [] to surround its index:

   $array[$index] = $datum;

When you set both to a list, surround the list with ():

   %hash = ( 1, 2, 3, );
   @array = ( 'a', 'b', 'c', );

Programming is as much about organization and communication
as it is about coding.

I like Perl; it's the only language where you can bless your
thingy.
