51# Our doc tests depend on quote which depends on proc-macro2. Without this line,
52# the proc-macro2 dependency of quote would be the released version of
53# proc-macro2. Quote would implement its traits for types from that proc-macro2,
54# meaning impls would be missing when tested against types from the local
55# proc-macro2.
56#
57# GitHub Actions builds that are in progress at the time that you publish may
58# spuriously fail. This is because they'll be building a local proc-macro2 which
59# carries the second-most-recent version number, pulling in quote which resolves
60# to a dependency on the just-published most recent version number. Thus the
61# patch will fail to apply because the version numbers are different.
