Could you explain the difference?

Simple, __traits or __treats as you called it is implemented by the
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.
