I got redundancy C ++

Hi Habr,
C ++ enters me into a stupor. I’m just hanging out over the monitor, looking out the window, sipping tea ... And I’m starting to feel sorry for the years spent pricelessly studying the C ++ standard, trying to write my front-end compiler. These tricky books C ++ In Depth. How indignant I was when I did not understand the code from the book Alexandrescu. How to write down all the postulates of Straustrup and their ilk. What for? Here I ask myself why I now know all this. More, I want to say that this language is merciless for a guru, not from a medical, not from an economic point of view! He does not justify the effort invested in his study - once. In practice, it is not economically beneficial - two. And nerve cells will confirm that accompanying someone else's plus code - it can be dangerous to health - three. Let there be randomly scattered metaphors, I write as is, from experience.


Here, for example, because of bizarre postulates: objects in methods to transfer as constant links.
Yes i'm writing
