In my real code, I had a struct that represented a database row with several
fields. I know it's not much more work (esp. with a good editor) to go from
this:

  MyClass = Struct.new('MyClass', :field1, :field2, ..., :fieldx)

to this:

  class MyClass
    attr_accessor :field1, :field2, ..., :fieldx

    def initialize(field1, field2, ..., fieldx)
      @field1 = field1
      @field2 = field2
      ...
      @fieldx = fieldx
    end
  end

...but it is a bit more work.

But the point for me is still the surprise of not having an instance var
inside a Struct (although it does make sense that this is probably pushing
Structs beyond their intended use).
