Rails - Nov 2007 - OpenHash class I thought I would share...

I love OpenStruct, but it has no ability to iterate over the members.
I had extended it, but recently I use this little class.  Anyone see
any issues with it ?

class OpenHash < Hash
  def method_missing(name, value=nil)
    key = name.to_s.sub(/[=?!]$/,'''').to_sym
    self[key] = value if name.to_s[-1,1] == "="
    return self[key]
  end
end

>> o = OpenHash.new
=> {}
>> o.a = 1
=> 1
>> o.b = 2
=> 2
>> o.h = OpenHash.new
=> {}
>> o.h.a = 1
=> 1
>> o.h.b = 2
=> 2
>> pp o
{:a=>1, :b=>2, :h=>{:a=>1, :b=>2}}
=> nil
