Isn’t putting a stack based pointer inside the class syntax easiest? Maybe I don’t understand but it seems to be you’re just swapping a pointer around.

After I had the idea this morning it’s appearing now that is more of optimization like “inline” or “constref" which basically says “this class exists only for this scope” so the compilers knows it can not call GetMem and call the destructor at the end of the scope. It’s not really a new model, just an optimization on classes which is meant to solve a very particular and frequent pattern of alloc on function start/dealloc on function end.

That sounds really good and simple to me but I believe me I understand why the compiler teams doesn’t like to add features and clutter up the language. It’s a hard call.
