Thanks for all the great suggestions. Here's the solution I've cobbled
together. It seems to work nicely.

I now define objects with the following specifications

(1) The GetProperty method has an all=all keyword that
returns a structure containing all of the paramters and
values of that object. (I know this works best when the
values are simple and not pointers and containers...)

(2) The Init method has an all=all keyword. If the user provides
an all structure when the object is first defined, then the
contents are used to set the initial values of the object.

I defined the following obj_copy() function

function obj_copy, a
a -> GetProperty, all=all ;Read a structure with all prameters
b = obj_new(obj_class(a), all=all) ;Create new identical object
return, b
end

While not a completely generalizable function, this will work for me
for now.
I also like the suggestion to make a Copy() method part of all object
definitions.
