Wondering about `cargo update —cooldown 7d`. Seems pretty straightforward…

We only recently bumped the MSRV past something where that is an option, and haven’t gotten to it yet.

Sounds good to me. Maybe the deprecation only happens in edition $next at first? (And in a clippy lint.)

Very curious on how you're going to do FSKit stuff from Rust. I previously looked into that and it seemed pretty painful?

Uplift `declare_interior_mutable_const` and `borrow_interior_mutable_const` from clippy to rustc · Issue #77983 · rust-lang/rust
In tokio 0.2, there was a footgun: if you created a const Runtime, then each time you called runtime.block_on() it would make a new runtime. This lead to confusing errors at runtime like 'reactor g...

Still feels like a lot of complexity. I wonder if the simpler thing wouldn’t be closer to: (1) introduce a new trait between Copy and Clone, maybe called Alias, (2) have a transformation insert implicit alias() (not clone()) calls where needed, emitting an allow-by-default lint when doing so.

Also by virtue of having a trait name and argument names, the barrier to switch from a Fn/FnMut/FnMut to a “real” trait should be pretty low.

My experience is that even the simple stuff is fractionally complex in one way or another. The power of dependencies is that you benefit from all the eyeballs running into bugs that will affect your project. “Things you didn’t know about Unicode”, but also names, URLs, zip codes, email addresses…

The main downside of Ghostty is all the crap about xterm-ghostty not being recognized across servers/accounts.

Getting some way of checking the compiler version by cfg will help eliminate one category of these at least.

I think this is pretty much what the EU CRA is trying to do.
