As a user of both rust and and C++, I certainly wouldn't consider the the lack of default constructors in rust to be a good thing. Especially for std types like Vec it is really annoying to have to initialize it explicitly.

That is a bad argument if you're comparing to a language that doesnt have a spec. Maybe a complete, exhaustive rust spec would be much longer than the C++ standard?

That is fair but orthogonal to the issue at hand, namely:
