The Edition Guide claims that await and try will be keywords in Edition 2018. On Discord, @scottmcm pointed out that one compatibility lint could check for all the new keywords. Right now we have async_idents to check for async, but it makes sense to just have one lint (rust_2018_keyword_idents?) instead of three, because there's not going to a situation where you would want, e.g., #[warn(async_idents)] but #[allow(try_idents)].

async_idents is already on the beta train, so if we do this, then we need to either:

  • (preferred) do it before the mid-September 1.29 cutoff and backport it to 1.29 beta, or
  • register_renamed for async_idents

I believe this should be fixed by #53685

Generalize async_idents to all new keywords
9e96419 
This commit generalizes the existing `async_idents` lint to easily encompass
other identifiers that will be keywords in future editions. The new lint is
called `keyword_idents` and the old `async_idents` lint is registered as renamed
to this new lint.

As a proof of concept the `try` keyword was added to this list as it looks to be
listed as a keyword in the 2018 edition only. The `await` keyword was not added
as it's not listed as a keyword yet.

Closes rust-lang#53077
