extends keyword instead of <superclass ... >

Hi,
Just a small note on
http://wiki.ecmascript.org/doku.php?id=strawman:super_in_object_initialisers
(reading currently)
Why not just to use already reserved `extends` keyword for specifying a
superclass? These XML-like braces looks not so elegant.
Coffee users the same classes syntactic sugar as planned for ES6:
http://jashkenas.github.com/coffee-script/#classes and also reuses
familiar (for all?) `extends` keyword of ES3.
P.S.:
This (XML-like syntax) relates also to other meta-properties/attributes
in object initialisers. I prefer to use @ instead:
let foo = {
@proto: bar,
@sealed,
move: # (x, y) {
...
}
};
Though, again, e.g. Coffee (on Ruby's style) users `@` for `this`. Does
JS need this sugar for `this`? In this case (since # is planned to be
used actively) meta-properties can be:
let foo = {
#proto: bar,
#sealed,
move: # (x, y) {
...
}
};
Dmitry.
