Predicate get_dict/5
Availability:built-in
[semidet]get_dict(+Key, +Dict, -Value, -NewDict, +NewValue)
Create a new dict after updating the value for Key. Fails if Value does not unify with the current value associated with Key. Dict is either a dict or a list the can be converted into a dict.

Has the behavior as if defined in the following way: 

get_dict(Key, Dict, Value, NewDict, NewValue) :-
        get_dict(Key, Dict, Value),
        put_dict(Key, Dict, NewValue, NewDict).

This predicate is misnamed. fork_dict/5 (as in source code forking) would be better: a new fork of the dict is created, after all.
