Subject: OpenStruct problem

OpenStruct class seems to be misbehave when it comes to hashing.

For example,
irb(main):008:0> o1 = OpenStruct.new
=> <OpenStruct>
irb(main):009:0> o1.val = "a"
=> "a"
irb(main):010:0> o1 = OpenStruct.new
=> <OpenStruct>
irb(main):011:0> o1.foo = "a"
=> "a"
irb(main):012:0> o1.bar = "b"
=> "b"
irb(main):013:0> o2 = OpenStruct.new
=> <OpenStruct>
irb(main):014:0> o2.foo = "a"
=> "a"
irb(main):015:0> o2.bar = "b"
=> "b"
irb(main):016:0> h = { o1 => 1 }
=> {<OpenStruct bar="b" foo="a">=>1}
irb(main):017:0> h[o2]
=> nil
irb(main):018:0>

If it's not possible to retrieve the same hash entry using
OpenStruct, what should I have to use instead?

Don't you think OpenStruct have to support eql? method
automatically?
