I put emphasis here on the resulting amount of lines of code necessary to implement something because I think that's the most important factor. I have shown that the implementation of a basic list using root_ptr takes no more than 30 lines of code.
Hmmm - but I can use std::list<std::shared_ptr<T>> in just one line of code.
Read the above as "I can >implement< a basic list by the means of root_ptr in 30 lines of code. NOT a list STORING root_ptr.
... And that's a repeated and unfortunate pattern. Every time the author gives an example of potentially useful application of root_ptr I feel like "why would I want that instead of the existing standard components?". The author might well implement a basic list in 30 lines but who'd want that when std::list is already available. Could that be that root_ptr is 20 years late? :-)
