Subject: $a = 5; $b = 'a'; print $$b

Hello,

I'm a seasoned Perl programmer trying to learn Ruby.

Is there a way a variable name can be variable? Like, how would I
rewrite the following piece of Perl code in Ruby:

	$a = 5;
	$b = 'a';
	print $$b; # should print 5

And can this be done with instance variables? I'm trying to do this:

class Series
    attr_accessor :sid, :handle, :name
    def initialize(vals) 
        vals.each_key { |key|
            @(key) = vals[key] # This doesn't work; syntax error
        }   
    end
end

s = Series.new({"sid" => 3, "handle" => "smoon", "name" => "Sailor Moon"})
puts s.name # should print "Sailor Moon"
