Cut off? Zealot?

Look, I got the email in my inbox, so I skimmed it to understand why I
got it and why the Rust list was Cc'd. I happened to notice your
(quite surprising) claims about Rust, so I decided to reply to a
couple of those, since I proposed Rust for the kernel.

How is that a cut off and how does that make a maintainer a zealot?

Anyway, my understanding is that we agreed that the cleanup attribute
in C doesn't enforce much of anything. We also agreed that it is
important to think about ownership and lifetimes and to enforce the
rules and to be disciplined. All good so far.

Now, what I said is simply that Rust fundamentally improves the
situation -- C "RAII" not doing so is not comparable. For instance,
that statically enforcing things is a meaningful improvement over
runtime approaches (which generally require to trigger an issue, and
which in some cases are not suitable for production settings).

Really, I just said Rust would help with things you already stated you
care about. And nobody claims "Rust solves everything" as you stated.
So I don't see zealots here, and insulting others doesn't help your
argument.

Cheers,
Miguel
