Кстати, в С++ все опять плохо, теперь из-за ABI (Application binary interface)
Library primitives, and even *language* operations like function calling, have overhead that we could easily quash ... if we forced a rebuild-from-source for a new release.
Like, unordered_map is 30-50x slower than a better implementation might be. std::regex is probably even worse than that.
The language can't really be the "Performance above all" systems language when we're leaving that on the table.

I believe this is the most important strategic question for the C++ community. https://t.co/WhYUQjIUhd Library primitives, and even *language* operations like function calling, have overhead that we could easily quash ... if we forced a rebuild-from-source…

В C++ никогда хорошо от ABI не было, ничего удивительного
Самая эффектная презентация из премированых статей. Результаты просто огненные и есть исходники.
