Okay, I've reread your posts. Would you say this is an accurate summary of your argument:
Python is aesthetic and Python is poor at prototyping, therefore aesthetic is bad for prototyping.
I'd appreciate if you also clarified the following:
Regarding my comment about prototypes morphing into production, that's only a red herring if a languages that are good at prototyping are necessarily poor at production (I don't agree with that). It's also a valid concern since it is is a common progression with today's software; the whole agile/iterative/refactoring methodologies are a response to this.
