Ian,
Can't a function call within a Handler do what you are wanting?

In other languages like JavaScript and Scheme that sort of thing is
referred to as a closure - here's an example from Wikipedia:
// Return a list of all books with at least 'threshold' copies sold.
function bestSellingBooks(threshold) {
return bookList.filter(
function (book) { return book.sales >= threshold; }
);
}
But I don't know of a way to even emulate closures in RevTalk (though it
might be handy at times if we could).
