Subject: changing class at runtime

I'm trying to find a way to arbitrarily alter the class of an instance at
runtime. The documentation didn't appear to have any clues.

Ultimately, I want to be able to do something like this:

class MyClass1
  def fnc1
    puts "fnc1 in class 1"
  end
end

class MyClass2
  def fnc1
    puts "fnc1 in class 2"
  end
end

a = MyClass1.new
a.fnc1
puts a.class

a.class = MyClass2
a.fnc2
puts a.class

Python lets you do it thusly: someinstance.__class__ = someclass

I figure that even if the solution turns out to be devoid of elegance, I
can toss it into a method of the 'Class' class to achieve what I want.

TIA
