Proc-macro2 removed the use of that feature in version 1.0.60. v1.0.47 is imported here through criterion. The fix seems to be upgrading criterion & serde:

huitseeker@sleipnir➜huitseeker/tmp/pasta-msm(main)» cargo tree -p proc-macro2 -i                                                                                                                                                      [9:01:38]

Not that updating criterion is out of the question, but why don't I see the problem? If I look into my Cargo.lock as it is now, I get version = "1.0.70" for proc-macro2. Is it possible that cargo update would solve the problem too?

My bad, it should, and does 🤦 : https://github.com/bheisler/criterion.rs/blob/f9ccd05caad4d068679074c3bc33c3f712ff2343/Cargo.toml#L23-L25 I should have had that 2d cup of coffee this morning.
