aggregate_properties_by_list — Selective dynamic class properties aggregation to an object
Aggregates properties from a class to an existing object using a list of property names.
The properties whose names start with an underscore character (_), which are considered private to the aggregated class, are always excluded.
The optional parameter exclude is used to decide whether the list contains the names of class properties to include in the aggregation (i.e. exclude is FALSE), or to exclude from the aggregation (exclude is TRUE).
