+Deferred Ideas
+==============

 New syntax for ``frozendict`` literals
 --------------------------------------
 
 Various syntaxes have been proposed to write ``frozendict`` literals.
 
 A new syntax can be added later if needed.
 
+Method to convert ``dict`` to ``frozendict``
+--------------------------------------------
+
+Different methods have been proposed to convert a mutable ``dict`` to an
+immutable ``frozendict`` with *O*\ (1) complexity.
+
+We consider that such method can be added later if needed, but it
+doesn't have to be added right now.
