Fixes #74.
I played around with the first solution I proposed there, i.e. defining all methods during the initialization by using
super
, but there are some behaviors ofRecursiveOpenStruct
that were too specific to make it work, like thepreserve_original_keys
option. The original implementation simply converts every key to a Symbol.So I went with the second option: override
Object#freeze
to create all methods before freezing the object itself.The gem could also provide a
#deep_freeze
that would freeze the object, as well as all its sub-elements, recursively.
