... sure, I usually do it somewhat like this:)

(In fact I've started writing an essay about that but didn't get much interest, http://www.vrspace.org/docs/zen_of_self-adaptive_code-jitsu.html)

And I use soft references so I don't need all objects in memory but keep some MRU cached etc etc.
However, when working with say 10000000 'neurons', I don't even have enough RAM for references.
It occurred to me that such a reference 'weight' would be quite usefull hint for decision what to keep in memory. In OO model such 'weight' could turn to i.e. simple integer referrer count divided by class tree depth. Or maybe more simillar to synapse weight - object access count (handle with care). Or something; I'm improvising:)
FTR simple MRU gives me about 97% cache hit rate. Well, my 2c, keep up the good work.
