For jinja2, it must be none and not None. No idea about Mako, though :)

@felixfontein mako wants None, I did not test jinja, so amended the commit to only touch mako templates

Sounds good! I must admit that I haven't tested the Mako versions...

I think None works in Jinja2 as well.

None works, but is None does not. At least, it used to not work...

import jinja2
print(jinja2.Environment().from_string('{% if None is none %}A{% else %}B{% endif %}').render())
print(jinja2.Environment().from_string('{% if None is None %}A{% else %}B{% endif %}').render())

This prints A and then dies with:
