I like it too. In fact I hate that "smart deleter" brings some overhwad,
even if it's quite small. Rule "do not pay for what you do not use"
simply do not allow it into language in place where it can bring most
benefit :( If only there was 0-overhead way to add deleter support in
runtime, not changing object (smart pointer one) type ...

That's OK. But not to clutter source code with my name I prefer name
"auto_storage" , as everything is inside pointer stack storage.

Would be great.
