I did:

But Walter thinks that enforcing object-value comparisons in a 
rather limited way is a feature. It is a feature... but it is the 
wrong kind of feature... ;) It is an oversimplified and 
ineffective solution.

A more sensible approach would be to use type-classes/concepts 
for defining what kind of comparison relation a class is required 
to provide and then deduce comparison operators based on what the 
programmer provides (e.g. if the programmer only provides a 
definition for "≤" then the compiler can deduce "<", ">", "≥", 
"==" etc.).

D moved into templates and generics without cleaning up  the 
language and is essentially ducktyped and macroish. Like C++. And 
Go (just in a different way).

But C++ might start on a change process with C++17/20. We'll see.
