- For both strict and sloppy object literals, both computed and static
properties no longer have any duplicate name checking.
I would like this the above to be clarified.
At the f2f we were talking about spread in object literals.
var a = {x: 1, y: 2};
var b = {x: 3, ...a};
However, reading the notes the context is lost and it seems like we are
suggestion removing the duplicate property check added in ES5 for strict
mode.
