I think you're right that Interpy and PEP 498 have a different, earlier binding strategy than say does. I've found the late / local binding of say() and fmt() convenient. Are there use cases where that earlier binding is valuable or critical? Your example highlights the binding strategy, but more typical would be: >>> def test(x=1): ... return fmt("{x}") ... >>> test() '1' >>> test(12) '12' >>> test('woobers') 'woobers'
