Ostruct relies on #frozen? to block modification. And also allows modification
of new members after having been frozen.

Attachments: ostruct.patch, ostructfrozen.rb
After freezing an ostruct one can assign to a new member.
One can also assign to any members if OpenStruct#frozen? is redefined thus that
it returns a non true value, or if the singleton class of an ostruct object was
modified in this very way before it was frozen.
