this is always double with C++.

At one point, it most definitely is easier to use now already than pre-C++14 or 11. Lots of those additions really make me enjoy using it (even more:) and often lead to less code which does the same while still not being harder to understand (often even better to understand) and having the same performance.

However, because of the backwards compatibility there still is cruft around which does make it harder to use because you basically need to know how to use it or in most cases that you shouldn't use it at all. Ideally one just wouldn't need to spend time / 'brain resources' on that kind of stuff. Simple example: I can still use std::auto_ptr. I won't because there are much better alternatives. I can still use std::tr1::shared_ptr. I don't, and I know what it is when I see it. But for a newcomer or slow learners this is just utter nonsense: need to figure out wtf tr1 is, why it exists, what to do with it, and so on.
