Traits seem, to me, a lot like generic functions and methods in CLOS (Common Lisp). It's just that CLOS doesn't bundle a group of generic functions into a trait, they're a la carte.

Yes they do, they are called protocols.

> Actually something like traits (as concept) is what powers COM, WinRT, the basis of Objective-C protocols that influenced interfaces in more common OOP languages.
So? Giving up Rust-Traits doesn't mean that I will give up on interfaces as a whole.
I don't like the way C++ does interfaces, for example, but that doesn't mean that my ideal language won't have interfaces.
Also the basis for one programming language that used to be widespread in the enterprise for quick and dirty solutions, VB and its ecosystem of OCX libraries.
It is more widespread that people think, because when many argue about OOP, they miss the full spectrum of how OOP is approached.
