VBScript, of course.

Hmm. Would it be possible to have a DOM property which was defined to
alias the underlying language hash ID in languages that support such,
and define a backwards compatible variant only for languages that
don't have it? Kinda a reverse language binding.

Nothing prevents the addition of hashCode to ECMAScript 3
implementations. I'm don't know VBScript and it's object model, so I
can't say anything about that.
