Try using newer version.  I can't explain everything for every
version.

irb(main):001:0> RUBY_VERSION
=> "1.8.1"
irb(main):002:0> RUBY_RELEASE_DATE
=> "2004-02-03"
irb(main):003:0> class Foo; def bar=(b); @bar = b; self; end; def bar; @bar; end; end
=> nil
irb(main):004:0> f = Foo.new
=> #<Foo:0x40347588>
irb(main):005:0> f.bar = 9
=> 9
