I don't believe you can override comma, and I'm also not sure an
ExpressionList is of general utility -- so far, all the places where we needed
such lists were method calls (like order_by()). I'd try harder to look for
APIs which keep it that way -- just off the top of my head,
Window(expression, *order_by)
(this probably doesn't work, Window() is more complex than that, but the
order_by=[...] suggested by Mads probably does)
