I remember that one of the recent(ish) versions of Runrev introduced

use them?
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).
The Engine Change Log included with the install covers changes back to
v3.0, and I don't see anything there like this.
Can you recall more details about the feature you're thinking of?
