This resembles certain forms of literate programming, like Haskell's "Bird style"[1] or Literate Markdown: [1]: https://wiki.haskell.org/Literate_programming https://wiki.haskell.org/Literate_programming [2]: https://ghc.haskell.org/trac/ghc/wiki/LiterateMarkdown https://ghc.haskell.org/trac/ghc/wiki/LiterateMarkdown I've dabbled with it and enjoyed it, but I really feel like it needs editor support to feel truly fluent (i.e. being able to preview the formatted version on the fly, being able to collapse the text blocks, etc.).
