Today I learnt about clippy::clone_on_ref_ptr, which complains about t.clone() on a Rc<Thing>. You write Rc::clone(t) instead, so it's obvious it's a cheap clone. It's a nice approach, because it makes the expensive clones more obvious.

I've heard of 'blub languages', where you don't realise that other languages have better abstractions until you've experienced them. I think the same thing happens with individual features. I've seen several C++ folks miss variadic generics in Rust, but I've not written enough C++ to feel it.

It's a small thing, but I'm much happier with --version in the latest version of difftastic. It shows the release number and the commit date. This gives you a reproducible build with age info. It also shows OS, arch and compiler, because those are useful in bug reports.
