Store deep and wide hashes in single level tied hash
DWH_File is used in a similar manner to NDBM_File, DB_File etc. In fact it depends on one of these. DWH_File expands the functionality to save not only the hash that is tied but also all the data that this hash contains references to - that is it’ll save all you list of lists and list of hashes and so forth. And what’s more, it will save objects as well - if they’ll comply with some very simple rules which don’t impose any limitations to their functionality or structure except that they can’t themselves be tied to anyone else. See the “Models” section of the embedded documentation for details.
