Both $hash->{$key} and $$hash{$key} work fine and this also works Although I'm
not sure why.... ${$hash}{$key}.
The reason ${$hash}{$key} works is because it's a generalization of
$$hash{$key}. The rule of thumb is:
1. start with $HASH{key}
2. replace HASH with a block: ${ ... }{key}
3. fill the block with a hash reference: ${$hashref}{key}
4. if the contents are simple enough, braces are not needed
I seem to have a lot of problems with the perl language in that there are so
many ways to accomplish (express) the same thing.... A wonderful feature but
sometimes confusing as hell (to me at least).
Consider reading 'perldoc perlreftut', a tutorial to using references.
