Description
void 
aggregate_properties_by_regexp ( object object, string class_name, string regexp [, bool exclude] )
     Aggregates properties from a class to
     an existing object using a regular expression to match their names. 
     The optional parameter
     exclude is used to decide whether the regular
     expression will select
     the names of class properties to include in the aggregation (i.e.
     exclude is FALSE, which is the default value),
     or to exclude from the aggregation (exclude is
     TRUE).
     
     The properties
     whose names start with an underscore character (_), which are
     considered private to the aggregated class, are always
     excluded.
