Thank you both for the quick replies. Ofcourse now I have some more questions.

1.) Can you explain the following code? How does$lang->$method(@$item); know which sub-routine to call?

2.) From looking at the output of Data::Dumper for the array and hash subroutines, it looks like this is stored in arrays or nested arrays. Im having difficulty understanding how to extract this data. It's nice that Data::dumper is smart enough to print the structure but how it does it Im not sure.

3.) Can this grammar be modified to allow the following entries?

$a = "hello"

$b = "world"

@array = $a, $b

%hash = key=>@array

etc...

Once again, thank you for your help!
