| 56 | # the proc-macro2 dependency of quote would be the released version of |

| 57 | # proc-macro2. Quote would implement its traits for types from that proc-macro2, |

| 61 | # GitHub Actions builds that are in progress at the time that you publish may |

| 63 | # carries the second-most-recent version number, pulling in quote which resolves |
|---|
| 64 | # to a dependency on the just-published most recent version number. Thus the |

| 65 | # patch will fail to apply because the version numbers are different. |
