Subject: YAML problem with Method pointers

It looks like YAML can't restore a Method pointer.  True? Or am I doing
something wrong here.  Is this a known Ruby bug or a limitation of YAML
or a Larry-is-a-goof problem? The following code frag fails on the last
line when it tries to load the YAML string...

class MyKlass
  def initialize
    @myMethodPtr = method(:myMethod)
  end
  def myMethod  command
  end
end

myObj = MyKlass.new

puts myObj.to_yaml  # YAML text generated but it's missing the Method
Info
$newObj = YAML.load( myObj.to_yaml )   # FAILS HERE

------ OUTPUT ------

--- !ruby/object:MyKlass
myMethodPtr: !ruby/object:Method {}

C:/ruby/lib/ruby/1.8/yaml.rb:133:in `transfer': allocator undefined for
Method (TypeError)
        from C:/ruby/lib/ruby/1.8/yaml.rb:133:in `node_import'
        from C:/ruby/lib/ruby/1.8/yaml.rb:133:in `load'
        from C:/ruby/lib/ruby/1.8/yaml.rb:133:in `load'
        from x_yml_builder.rb:12

Thanks,
Larry Fast
