So what's your point?
Another example. I had asked for a TypeTrait is_integer and also supplied code for it (https://github.com/boostorg/type_traits/issues/186). The point is that is_integer only returns integer (no character, no bool). John immediately closed my request "We are not responsible for that". Instead of admitting a mistake (of course I make some myself) and saying "we forgot/didn't think of it, we'll do it", the only answer is "we don't care". That's thinking from the wallpaper to the wall. As I said, boost used to be progressive, but now when you make a suggestion, all you get is "We're not responsible for that/we're not interested in that/we might have to change something that's not possible" And this even with such a simple TypeTrait. Single file. No dependencies. And on the other hand, libraries with the most severe buffer overflows (charchonv) are included, where obviously no tests are carried out at all.
