Basically, I want to do this:

class Series
    attr_accessor :sid, :handle, :name
    def initialize(vals)
        @sid = vals['sid']
        @handle = vals['handle']
        @name = vals['name']
    end
end

without having to type out the @x = vals['x'] line for each and every
instance variable, since I have other classes that have a lot of
variables.

I tried eval(@key = vals[key]) and eval(@key) = vals[key] but those
didn't evaluate correctly.
