[DGD] Object handling

[Steve Wooster]

     I'm trying to plan writing an object handler, but I've come across an 
issue (pardon the pun) where I'm not sure what would be better... I'm 
trying to decide whether or not updating the auto object and doing a full 
recompile should be unnoticeable, or whether it should affect inheritance 
"trees" (is hierarchy a better word?).

     Let's say you have ObjectA which inherits ObjectB, and they both 
inherit Auto. You make a change to ObjectB, so now there's ObjectB_Issue2 
which inherits Auto, but ObjectA is still inheriting the old version of 
ObjectB. Now, let's say you make a new version of the auto object and do a 
full recompile... Should ObjectA still inherit the old issue of ObjectB 
(but with both now inheriting the new auto object), or should it inherit 
ObjectB_Issue2? It'd be much simpler to do the latter, but I worry about if 
that could make updating the auto object less transparent, as it would 
bring inheritance "trees" up-to-date as a side effect (and possibly an 
undesirable one). Any opinions? Thanks!
