Subject: Re: Get OpenStruct attributes

Given this setup:

>> require 'ostruct'
=> false
>> o = OpenStruct.new
=> #<OpenStruct>
>> o.field = "this"
=> "this"
>> o.fold = "that"
=> "that"
>> o
=> #<OpenStruct field="this", fold="that">


The "nice" way:

>> o.methods - Object.methods - OpenStruct.instance_methods
=> ["fold", "fold=", "field", "field="]

Or maybe go one more level, to kick out the attr= methods:

(o.methods - Object.methods - OpenStruct.instance_methods).reject
{|method| method =~ /=$/ }

The "dirty" way:

>> o.instance_variable_get("@table")
=> {:field=>"this", :fold=>"that"}
