An array of every object loaded on the mud is returned by objects().
Note that if the system's maximum array size is set too low, objects()
will truncate its array, in which case it might not be too useful.
If the optional 'func' and 'ob' parameters are given, then ob->func()
is called with each loaded object as an argument. If the function
returns nonzero, then that object is returned by objects(), otherwise
If 'f' is given, it will be called on all the objects as above. For
example, objects( (: clonep :) ) returns a list of all the clones in
