It is now possible to cause class constants - values which are present
in an object which are the same as the class member of the same name -
to be hidden in the output. This can reduce the size of the output by
hiding information that can be obtained from the source itself.

Long lists and dictionaries are another place where the output can
become cluttered, and it is unlikely that the reader will want to check
the values beyond basic members of a dictionary, so these values can
be truncated as well - they would be truncated at the non-string limit
anyhow. Because the truncation happens at the item level, as well
as the total string level, individual items which are very long can
be kept from swamping the output. Additionally, the enumeration only
happens for sufficient items to meet the configuration, so the whole
dictionary or list does not have its representation generated only
to be truncated.
