let x = { b: 1, extra: 2 }
let xx: { a, b }  = { a: 1, ...x, z: 3 } // error for 'z', no error for 'extra'
Object literal freshness errors with spreads Previously, object literals with spreads in them would not issue object literal freshness errors. Fixes #13878 2017-02-06 17:47:11 +01:00			`let x = { b: 1, extra: 2 }`
			`let xx: { a, b } = { a: 1, ...x, z: 3 } // error for 'z', no error for 'extra'`
