It says that Python is already adequately expressive to allow it to 
solve all solvable problems: more briefly, "Python can already do 
everything". Hence there is no need to change the language.

Of course I use this as a /reductio ad absurdum/ to try to show you the 
falsehood of your position. Sadly I fear this will simply result in 
another response which won't move the dialogue forwards.

It seems to me you either don't understand the words "obvious" and

I believe I have also suggested that the phrases of the Zen aren't to be 
taken too literally. You seem to distinguish between "obvious" meaning 
"obvious to Steve but not necessarily to me" and "really obvious" 
meaning "obvious to both Steve and me". So where does the subjectivity 
creep in? And are you going to spend the rest of your life arguing 
trivial semantics?
