Can you back this up please with either an example or a web reference. BTW, Java <-> C/C++ does not behave this way. The term "object" should probably clarified before we go too much further. Both python and java languages use handles a.k.a. references, so you have a layer of indirection to protect against "bad things" from happening. When you "delete an object" in C++ this merely triggers some activity at the holder of the true end object. I was the 2nd person in the world to write a full Java virtual machine, probably the first to do it alone, complete with JNI, so let there be no doubt about my comprehension there. Mine was on the market well before Microsoft learned their $20,000,000 lesson about contract law. I could have saved them a lot of money.
