| # Our doc tests depend on quote which depends on proc-macro2. Without this line, |
| # the proc-macro2 dependency of quote would be the released version of |
| # proc-macro2. Quote would implement its traits for types from that proc-macro2, |
| # meaning impls would be missing when tested against types from the local |
| # proc-macro2. |
| # |
| # GitHub Actions builds that are in progress at the time that you publish may |
| # spuriously fail. This is because they'll be building a local proc-macro2 which |
| # carries the second-most-recent version number, pulling in quote which resolves |
| # to a dependency on the just-published most recent version number. Thus the |
| # patch will fail to apply because the version numbers are different. |
