This is yet another module that lets you access or change the elements of a
hash using methods with the same name as the element's key. It follows in
the footsteps of Hash::AsObject, Hash::Inflator, Data::OpenStruct::Deep,
Object::AutoAccessor, and probably others. The main difference between this
module and its forebears is that it supports tied hashes, in addition to
regular hashes. This allows a modular division of labor: this class is
generic and treats all hashes the same; any special semantics come from the
tied hash.
