// Welcome, Build Wrangler!
//
// A failure in this test indicates that there is a potential ABI breaking
// change in the Standard Library. If you observe a failure, please reach out to
// the Standard Library team directly to make sure we resolve this quickly!
//
// Instead of XFAILing this test, please consider extending the list of expected
// changes at the bottom. (In addition to ignoring the current set of ABI breaks,
// XFAILing this test also silences any future ABI breaks that may land on this
// branch, which isn't ideal.)
//
// You can find a diff of what needs to be added in the output of the failed
// test run. The order of lines doesn't matter, and you can also include
// comments to refer to any bugs you filed.
//
// Thanks! -- Your friendly stdlib engineers
