  // For example:
  //
  //   semver.intersects(`<7.0.1`, "7.0.0-beta.0") // false - surprising
  //   semver.intersects(`<7.0.1`, "^7.0.0-beta.0") // true - expected
  //
  // This is because the first falls back to
  //
  //   semver.satisfies("7.0.0-beta.0", `<7.0.1`) // false - surprising
  //
  // and this fails because a prerelease version can only satisfy a range
  // if it is a prerelease within the same major/minor/patch range.
  //
  // Note: If this is found to have issues, please also revist the logic in
  // babel-core's availableHelper() API.
