Generally I will use lists for fast and loose vectors, in unoptimized code, and tuples for more firmly "typed" data, or performance enhancements. I don't need more and I don't need less: the two seem well-balanced for me. As someone who abhorred Perl, Ruby looks a little frightening. Python looks and feels clean, especially for blocks of data. In OO though, self.whatever appears more frequently than I'd like.
