Hello,
    I've recently wandered over from the Perl side of the programming world, 
and I'm curious - Is there some sort of use strict in Ruby that requires you 
to pre-declare your variables?... 

    Also, what ways are there of implementing Perl-style nested data 
structures? ... 
I'd like to be able to nest hashes inside of arrays, and vice versa.. How can 
I do so in Ruby? :-)

                                                -malander
