Black in there as a linter - I’ve had hood experiences with that

It's actually already present in 7.x, just opt-in. And you should be able to hook any formatter you want, black just appear to be popular.

No problem with Black per se - it's my default linter - but latest inclusion with IPython 8.0 seems to break in a Docker environment:

    Generating grammar tables from /usr/local/lib/python3.10/site-packages/blib2to3/Grammar.txt
    Writing grammar tables to /root/.cache/black/21.12b0/Grammar3.10.1.final.0.pickle
    Writing failed: [Errno 2] No such file or directory: '/root/.cache/black/21.12b0/tmpx51kjom5'
    Generating grammar tables from /usr/local/lib/python3.10/site-packages/blib2to3/PatternGrammar.txt
    Writing grammar tables to /root/.cache/black/21.12b0/PatternGrammar3.10.1.final.0.pickle
    Writing failed: [Errno 2] No such file or directory: '/root/.cache/black/21.12b0/tmp80hsbuff

I believe this is the issue:

Not entirely clear what the reasons are for adding the Black dependency to IPython....

Because now IPython will automatically reformat you code while you type it with black ?

It should though fail gracefully if it can't import black.

What's a hood experience?

It's like when programmers put their black hoodies on to become hackers, and type so fast they swap G and H. Like you've seen Mr Robot ?

haha . Too late for the edit unfortunately.
