[DGD]Tracking auto_object usage

[Kevin N. Carpenter]

Ah... the light finally goes on.  So, in order to spread things
out, a database of master objects could be created, another of
inherited objects, or, for example, a database could be created
for every separate directory things are inherited or cloned from
in order to spread the information between objects, minimizing
the chance of exceeding array_size.

I think I've been stuck in an object oriented programming rut,
insisting that objects know everything about themselves.

Thanks!

Not necessarily -- it could be maintained in a completely independent
database, with the added advantage that the database can choose to
distribute the data across several objects.

My turn to clarify my writing.  Whether or not the auto object is
destructed is important in my version of the object registry, but
may not be so in yours.  What matters is that, from a masked
compile_object() function, a simulated driver->inherit_program()
call can be performed -- or rather, the relevant portion of
inherit_program() can be copied here.
