I'm confused by your comment. The author of this blog post had problems with the experimental design in the paper you're talking about. Specifically, he said: "However, since the scripting language group had significantly different (and easier) environment than the C-like language group, it’s hard to say how much of the measured difference in implementation time is from flaws in the experimental design and how much is real." Said another way, the experimenters picked a task which some of the languages were designed for. Which sounds rather like the point you're trying to make, too. Did you confuse the quoted abstract with this author's comment?
