Yes, they are. They are basing their argument by comparing Rust Result against C++ exceptions in the context of general error handling whereas I pointed out that there are actually two classes of errors and both of which are addressed their own appropriate mechanisms in both Rust and C++.

What parent comment tried to (wrongly) imply, and your comment as well, is that exceptions in C++ are (commonly) used as a control flow mechanism. And they are not.
