Description
My existing code has:
#[allow(unreadable_literal)]
Which produces this warning on the beta channel:
lint name `unreadable_literal` is deprecated and may not have an effect in the future. Also `cfg_attr(cargo-clippy)` won't be necessary anymore
note: #[warn(renamed_and_removed_lints)] on by default
help: change it to: `clippy::unreadable_literal`
However, changing it to clippy::unreadable_literal
causes the following:
scoped lint `clippy::unreadable_literal` is experimental (see issue #44690)
On nightly #![feature(tool_lints)]
can be used as an escape hatch but that's not an option on beta.
IMO neither Nightly nor Beta should generate warnings to change code to something that requires a feature flag. The existing code was valid for the stable features of the language.
