error: An unknown error occurred
Caused by:
Feature `pretty` depends on `syntex_syntax` which is not an optional dependency.
Consider adding `optional = true` to the dependency
GitHub's default timeout is 6 hours. Recently some of my GitHub Actions
jobs have started randomly stalling for that long, which is inconvenient
because it ties up a chunk of my runner quota. It apepars to be very
rare for a job to recover after stalling. It's better to time out
quicker and retry on a different runner.

For whatever reason, the #![cfg_attr(feature = "cargo-clippy", allow(let_underscore_drop))]
attributes already in the code stopped working in the most recent nightly (2022-09-03).
