The project looks like it died unfortunately, but I think they did end up adding Python support before that happened. Might be worth checking out.
My opinion is that I get very close of this REPL style with a notebook and (right click on notebook tab in Jupyter lab) open console for notebook.
This opens a REPL (iphython console) alongside the notebook. The you can code all kinds of Clojure stylistic Python ways using nested dictionaries.
You have to make sure to copy paste you finished code into the notebook or other .py file not to loose it, but it’s minor.
[0] Admittedly LightTable was pretty buggy so it wasn't all fun and games. But still - I would love for my day-to-day development environment (Dart/C++) to look like that.
You can also write notebooks with clerk, which gives you a whole bunch of data visualization utility and renders to a browser (via websockets). Also has a static html export. Cool thing here it’s that it uses just normal Clojure files, so all your tooling just works.
There is a Haskell IDE available in the MacOS Apple Store than has a similar live view feature. I don’t much use this IDE, but it is cool.
