object FunctionMapJournal

An implementation of a journal backed by a map and a key-value computing function.

The FunctionMapJournal stores a map of keys and their associated values, as well as a function f that computes the value for a given key. It provides methods to compute values, append to the journal by applying the function f to a key, and create new instances with updated maps.

This class is designed to be used in scenarios where values for keys need to be dynamically generated or updated using a predefined function.
