the language currently stands. TG1 is no longer accepting proposals,
we're working on the ES4 reference implementation, and we're expecting

Folks,
I'm trying to create a Yacc grammar for ES4 and I have trouble
understanding the notation used in the spec.
For example, there's
alpha = { allowColon, noColon }
beta = { allowIn, noIn }
gamma = { allowExpr, noExpr }
and then
ParenExpression ( AssignmentExpression /allowColon, allowI
Thank you... --lars

In IE, Firefox, Opera and Safari, the character sequence as a line

Some demos:

Is this something that can be specced in ES4? Or is the intent to require
UAs to have a switch such that they can

With the proviso that the program unit proposal has still to be fully
specified and debugged, I believe the following should work:
Somewhere:
unit Beget {
internal package Beget {
Object.prototype.beget = function (o) { /* what you expect */ }
