  -### Batching breaking changes to libsyntax
  -
  -Due to the lack of stable plugins, making changes to libsyntax can
  -currently be quite disruptive to the ecosystem that relies on plugins.
  -In an effort to ease this pain, we generally try to batch up such
  -changes so that they occur all at once, rather than occuring in a
  -piecemeal fashion. In practice, this means that you should add:
  -
  - cc #31645 @Manishearth
  -
  -to the PR and avoid directly merging it. In the future we may develop
  -a more polished procedure here, but the hope is that this is a
  -relatively temporary state of affairs.
