Hi folks! Thanks for shipping a new release with fantastic type annotations - very much looking forward to that. :)
I've just tried upgrading, but I'm running in the following regression on the way:
{% set output %}
{% for x in [1,2,3] %}
hello
{% endfor %}

I've skimmed the Changelog, but couldn't identify anything that may point me in the right direction. The traceback is a bit above my head. Please let me know if I can help with anything else! 😃
It's possible to convince Jinja2 that everything is ok by first defining the inner loop variable:
{% set x = None %}
{% set output %}
{% for x in [1,2,3] %}
hello
{% endfor %}
{% endset %}
{{ output }}
