Yes, thank you. When you use generics for a sortable collection class, that makes sense--it's a perfectly reasonable application of the technology. Problem is that "clever" programmers go hog-wild with generics and create APIs that resemble Greek tragedies where everybody dies in the end.

I think that the Go core team acknowledges this tendency, and that's why they resist adding features which tend towards complexity/abuse when those "clever" programmers get ahold of them. Sure, it means some minor pain when implementing the Sort API for your class. The unseen benefit is that you don't get the horrific abuse of generics that I'm seeing in my current Java job.
