Thank you for this post. I was in a discussion of Ruby vs. Python at
lunch today. The consensus was that Python was much better than Ruby in
all ways. Since I know very little about Ruby, I had nothing to add to
the conversation.
I have struggled considerably with lambdas since taking up Python. I'm
still not really comfortable using them in production code. I agree
that Ruby's style is more intuative and easier to use. I wonder if a
future version of Python could adopt this style.
Regards,
Barry

PS
Your response to the recent unpleasantness was exceptional. I tried to
be civil in my disapproval, but deflecting the thread back to a
constructive, Python-based topic was more effective, I thought. Thank
you again.
