I'd consider this a tad cleaner - although it is not really rock solid:

irb(main):015:0> x.methods - x.class.instance_methods
=> [:foo, :foo=]
irb(main):016:0> x = OpenStruct.new
=> #<OpenStruct>
irb(main):017:0> x.foo = 1
=> 1
irb(main):018:0> x.methods - x.class.instance_methods
=> [:foo, :foo=]

Kind regards
