// assert.doesNotReject: fulfillment passes; a rejection MATCHING the
// expectation (or with none) throws "Got unwanted rejection" with the
// actual message quoted; a NON-matching rejection rethrows the original
// reason untouched. A string expectation is the message form; regex
// expectations test String(error).
