# For fully intuitive multicreate any relationships in a chain
# that do not exist for one reason or another should be created,
# even if the preceeding relationship already exists.
#
# To get this to work a minor rewrite of find() is necessary, and
# more importantly some sort of recursive_insert() call needs to
# be available. The way things will work then is:
# *) while traversing the hierarchy code calls find_or_create()
# *) this in turn calls find(%\nested_dataset)
# *) this should return not only the existing object, but must
# also attach all non-existing (in fact maybe existing) related
# bits of data to it, with in_storage => 0
# *) then before returning the result of the succesful find(), we
# simply call $obj->recursive_insert and all is dandy
#
# Since this will not be a very clean solution, todoifying for the
# time being until an actual need arises
