> It was never documented that you can override variables from higher scopes
But you could, and people did... because that's what people do: they try stuff that seems reasonable and if it works they use it. And then someone "fixed" it in a minor release and things started breaking. BTW the error message is
KeyError: 'undefined variable: 0'
Fun way to spend an afternoon, I can assure you.
I used Jinja2 happily for years on a web app, but that thing pretty much just styled a page for flash to sit in and drew some forms and menus. I use it now via Ansible and have come to despise it through and through.
