A '''deep [dict%|%dictionary]''' is a dictionary in which each value is [deep
list]:  Each key has the same reprentation it would have in a standard [dict],
and each value is either a simple value or a deep dictionary.  A simple value
is represented as a list containing only one item.



** See Also **

   [scripted dict]:   Scripting a deep dict in a manner similar to [scripted list].



** Implementations **

   [ycl%|%ycl dict deep]:   Provides `get`, `merge`, `pretty`, and `set`.



** Description **

Unlike a standard Tcl dictionary, a '''deep dictionary''' is suitable for
communicating an ordered tree without prior agreement between the parties about
the exact shape of the tree.  A '''deep dictionary''' can be unambiguously
merged into another deep dictionary.
