Nice, I'll give a try :-) IMO it's another step toward a transformation from classic shells to modern REPL, xonsh is one, eshell (Emacs) is another and probably many others exists. Traditional shells have some nice things mostly due to the power of UNIX software, but also limitations for the very same reason. Personally having choose to live in Emacs I notice a significant reduction of shell usage, eshell included, but it still can't substitute a real terminal for me, I tried xonsh and find the same: sometime python power rocks, sometimes does not. Perhaps we still need many new step before achieve a new game changing interface...
