My first answer was glib, sorry. I'm proposing `with' as a replacement

Once again, it's absolutely the same approach which I showed yesterday with
using `extends'
(https://mail.mozilla.org/pipermail/es-discuss/2011-November/018478.html).
David is talking about the proposed<| operator, to replace that with
`with`, initializing an object with a given object as prototype. Not
extending... anything.
As well as I do.
When `extends' keyword is used in other langs for inheritance, does it
extend something in respect of copying own properties? Of course not.
It's just links an object with its prototype/class. Exactly for this it
was reserved in ES.
`extends' is the best in respect that it's used for exactly this purpose
in many other languages, and therefore, other users will fill familiar
with it.
I can accept `with' for mixins as was shown in previous letter.
Dmitry.
