Nitpick : > 1. Removing structs and interfaces (in favor of what? Java-style classes and interfaces?) would make Rust more verbose, less of a systems language, and slower at runtime due to the indirect dispatch. Classes and interface can be implemented without indirect dispatch...

Only if you monomorphize interfaces—which gives you Rust's traits.

No. THe fundamental difference is that rust traits cannot convey structural information , classes (java and c++ can)

There's an open (and desired) RFC for this. It's not likely to happen soon since it's not a super high priority, but I'd be willing to bet it gets merged in the future.

Fair enough, as long as we agree that classes/struct in C++/java a quite a different beast than just monomorphic traits.

Absolutely, you're totally right with regards to today.
