Hi,

interesting video, thanks Arne. Nonetheless have to shed some water into 
the wine:

As we've seen it's possible - but is it really easier then using a plain 
shell?

Also: it isolates your setup and configuration from that of your 
colleagues - in case its author is absent, it will be hard to take over 
for the others in an enterprise.

And some more basic concern: the underlying literate programming 
paradigm seems pointless WRT examples given in video. Why comments in 
natural languages should be preferable over code? Code has the purpose 
to be less ambiguous, it's a kind of math. While natural language gives 
way to interpretation, i.e. misunderstanding of all kind. Maybe literate 
programming was of interest in earlier times in a world of low level 
coding. Higher languages are adapted at human mind, let's use them.

Cheers,

Andreas
