python - So what exactly does “from __future__ import barry_as_FLUFL” do?

Question

I understand it's an inside joke that's meant to stay (just like “from __future__ import braces”), but what exactly does it do?

Answer 1

It's related to PEP 0401: BDFL Retirement

Barry refers to Barry Warsaw, a well-known Python developer. The from __future__ import barry_as_FLUFL basically replaces the != operator with <>.
