FWIW I've been semi-actively designing a language of that sort, which I call Fawlty, since about February of this year. I was planning to start writing about it in July but then all the PSF drama stuff happened and I didn't want people to assume incorrectly that the idea was motivated by my disappointment with the community.

In fact, I'd been thinking about doing it since probably November of the previous year - and it's motivated by long-held beliefs that

Python's design falls short of the Zen;

several of the most common beginner pitfalls could and should be avoided by syntax changes and by a different approach to parsing the code; and

the standard library is full of ancient APIs that look terrible because they're motivated by C and Java designs that used to be the best we had but seem highly unidiomatic now.

It was somewhere in November or December last year that I first wrote those thoughts down more concretely (with details about what those pitfalls are etc.).

Given that pace of progress, however, I've more or less given up on ever expecting myself to publish something usable - by myself, at least. I've decided for now that it will be more practical to add blog posts about my ideas to the queue, and possibly see about my own implementation later.

With a name like Fawlty, aren't you duty bound to derive the language features from Eiffel and Sather?

If you're going to escape from Python, I think you need something more like Plissken.

I don't think so; if you recognize "Fawlty" as the name of a tower then you equally well recognize Fawlty Towers as a spiritual successor to Monty Python. The goal isn't to "escape" but to suggest that this is a new effort with the same background principles.

I have found Nim more useful/usable than Python + Cython since about 2014 for my personal use cases and almost always much more efficient on a "per unit of effort basis" than Go. At least if you are willing to write whatever code you need or link in C/C++ instead of relying on people gifting it to you.

I think the ecosystem leadership position Python finds itself in lately may well make Py-core silly enough to think "our users will tolerate our breaking-all-their-code antics no matter what". I suggest a more consenting-adults alternative here: https://news.ycombinator.com/item?id=41790766
