I don't think we want to do any special-casing based on the name (or lack thereof) of a constant. This rule applies to all non-associated constants and should be documented as such. |
Especially since it seems that there is no test in rust-lang/rust that covers the unamed constant case (even though the implementation covers it). rust-lang/rust#93838 (comment)
