You can just use ordinary object-creation syntax. The syntax you're
referencing is a shorthand, specifically for the limited, but common,
case where you want to add a field with the same name as a variable.

You can just write:
```
var d = {
a,
b,
c: e.c
};
```
(Assuming that's what you meant, and not `c.e` for the last field's value.)
