Hi.

I've been wondering if I can instantiate during execution, I have this
subclasses, but I don't know how to do it by their name as a string.

This is what I mean:

class superClass
...
end

class subClass1 < superClass
...
end

class subClass2 <superClass
...
end

class caller
   type = ['subClass1','subClass2']

  def create_class(var)
    #instantiate class type[var]
    newClass = type[var].new # ?????
  end
end

I don't wanna do it with a case clause, cos I don't know when I'm going to
add more subclasses.

Any idea?
