Just FYI: those thingies are called hashes. The legacy name would be 
associative array.

Wow, my compliments. The very first time that using Data::Dumper actually 
may do something useful (formats the data more nicely). Still, why you are 
passing a reference is beyond me.

Excuse me? If (using the same examples as for your Python section)
    print "Mary is $a{mary}";
    delete $a{vicky}; print %a;
    print keys(%a);
    exists $a{mary};
is too complex for your to cover, then I strongly suggest you stop posting 
your "explanations".
