def [] key
  real_key = Fauxsql.dereference_fauxsql_key(key)
  Fauxsql.resolve_fauxsql_attribute super(real_key)
end

#[]=(key, value) ⇒ Object

We dereference and resolve the key because in Ruby not any object can be a hash key. Even a DataMapper record.

#eql?(other) ⇒ Boolean

Always being not eql is expensive TODO make this work without this hack

Returns:

  • (Boolean)

#keys ⇒ Object

VERY VERY SPECIFIC to the marshal dump format. Probably brittle.
