GoPlus – The Go+ language for data science

Also, most data scientists presumably have some advanced math background so it's akin to reading set-builder notation (albeit with listcomps the sets are sometimes nested). Your listcomp reads:

{x : y ∈ z, x ∈ zz | y ∈ x}

If you've read enough statistics/ML papers, this becomes second nature.

As someone who breathes that style of notation, there is excellent support in vim and emacs for custom display for readability. Conceal syntax in vim¹(builtin for rust/help/$few_others and external such as vim-cute-python²), and pretty-mode³ in emacs. I'm sure similar things exist in other editors too, but I don't use those ;)

You don't get the exact representation in your example with the things I've mentioned, but if you're used to a more "mathy"-style they really are quite nice. YM[and taste]MV.

Interesting. I didn't know that!
