The point is that the diagrams you linked to don't tell you anything about the semantics Well, I'd say they do provide a strong indication at least. arbitrary and subtle differences between things that should be the same It seems Python would need quite a truckload of such subtleties to make up for the complexity difference reflected in the graphs alone. And since one of its core design-goals is to avoid subtleties like that I think the graphs were a valid vehicle to illustrate my point. Lambda is ofcourse a well-known wart in Python, but honestly, if we start wart-counting here then I think the comparison would end even worse for Ruby. For the record: I'm obviously a python guy but have also used rails and sinatra before. I'm by no means a ruby-hater. It's just that I couldn't let the statement "Python more complex than ruby" pass without speaking up. Because, as I tried to illustrate, I can not imagine a metric by which that would be true.
