Simple, __traits or __treats as you called it is implemented by the compiler. But std.traits is all implemented in the standard library as user D code. If you can do it with std.traits you should. Otherwise __traits. So std.traits is a bit higher level and there are more things available there as adding more __traits is a bit rare. So for example to get All Members of class I should use allMembers from __traits, because it's seems that std.traits do not have such future. Yes, you can think of __traits as the basic building blocks the compiler provides, and std.traits as providing more features using those building blocks. -Steve

Question about __treats
It's seems that __treats is language keyword that help to get info from compile-time. But there is also lib named std.traits and I can't understand difference https://dlang.org/spec/traits.html https://dlang.org/phobos/std_traits.html Could you explain the difference?
