It reminds me of Emacs org-mode in terms of the underlying structure and output. On the other hand, I'm not convinced that pytonic semantic white-space is an improvement over org-mode's use of more explicit markup. Maybe it's because for me there's a mental friction between the indentation of a line and it's left justified output.
Good luck.
