Subject: [ruby-talk:26141] Passing class names to constructors.

If I want to create a variable number of objects, all of
subclasses of one class, then how do I do that?
Eg in my knots example I might want

class TangledRope
    def initialize(knotclass = :Knot)
        mess = Array.new()
        (10*rand()).times do {
            mess.push(knotclass.something.new())
        }
end

so how do I turn the symbol into the class, so I can do things with it?
I don't like the obvious way: Deliver Us From Eval!  :-)
