If by "broken" you mean: will make a significant number of existing
pages break, then I'll have to agree. I wouldn't mind if the scope
chain hack was removed, though.

What I mean is that the methods and variables of the object
that is the execution context should always be included in
the current scope chain.

I don't see the problem. If you want to access the properties of the -
this - object you have the - this - reference to use for the task. That
is specified and I am yet to hear of a browser where it doesn't work
(and if I do I will regard that browser as broken).

Otherwise the desire to use a non-standard, inconstant and not
universally implemented feature of web browsers is usually rendered non
error producing with feature detection, though the overhead in doing
that makes the use of the - this - keyword look like the simpler option.

My point is that you shouldn't have to specify "this" in this case.
I specify it most often just to make the intent more clear to
the person reading the code. The other valid uses are to pass
a reference to the current object or to distinguish between arguments
and object fields in a constructor.

It works in all versions of IE, Netscape, Mozilla and Opera that
I've ever had installed. In which broken browser(s) do you need
to specify "this" to access the attributes of the object that is
the current execution context, or in which broken browser(s) is
the form element object not the execution context of its event
handler?
