Something like `var foo = {}; foo.bar ||= 3` would be very useful.
But not sure how something like `obj['name']['maxlength']` be reduced to
shorthand check if 'name' is not defined.

notation for attribute creation?
Unless I misunderstood your idea, `||=` makes me naturally think about
`+=` so if
`i += n;` means `i = i + n`
then
`o.name ||= value` means `o.name = o.name || value`
and this would be, according with all these years in ES3, the least
surprising behavior
