The article sounds to me, like Zed is saying Python's usefulness to him is mainly as an educational language, not so much a "daily" language. Is this right?
I use Python at work, and since I do I tend to not use it at home on my personal projects. That makes sure there's no conflict of interest with my employer. It also keeps me sane so that I don't get into a rut with my ideas.
These days I'm going with C and Lua. For example, I'm starting this project:
LPTHW is a good goal for beginners but what about the intermediate ones? I know how to code but when I see mongrel2 or any other opensource code I have no clue how to start integrating them. There may be others like me so when are you planning to write a not-so-advanced-book/tutorial for the intermediate coder who can recognize a pointer from his function.
The context right before he said that was that platforms are the interesting things, not languages. He's a Python user at work so he's getting his daily dose, but mixes things up at home.
He then goes on to say some of the quoted stuff about punctuation/structure. I took it as programming languages in general aren't an interesting topic to him, but Python caught his eye and actually interested him for the educational value.
Zed can obviously speak to that better than I. I just pretend I know how to interview and write :)
