Proposal: Numeric literals in object keys

[AldoMX]

With the current spec, the following JSON is invalid because the keys are not a valid identifier name:

{
  employeesById: {
    1: { name: "Huey", age: 30 },
    2: { name: "Dewey", age: 29 },
    3: { name: "Louie", age: 31 }
  }
}

This ticket is to propose allowing numeric literals alongside identifier names for object keys.
