Reload text?

What difference does this make?  Besides I need a lot of power, hence
compiled, optimized code.

I'll help you out: using a language provided persistent object-store
for saving state upon termination.  We've so far discussed programs
running in a shared memoryspace, so saving during runtime isn't
really theoretically interesting.

Mebbi, I don't know Greg.  I only "know" what I read.

Well, anyone attempting to introduce neural nets without running
separate prototypes for quite some time would most likely fail anyway..
:^)

Of course, what one has to think about is whether one need browsability
(for all objects do ...) or other type of functionality. So a list
cannot easily be swapped out for a hashtable if order is important...
