You have raised a good discussion point or two, but I am not inclined to engage with them due to the tone you've created with the rest of your comment.

Would it be productive to jump into a thread on a Ruby article and puff your feathers about how you've always been able to do this in Perl, and also in Python 4 you can do XYZ? I don't think so.

For whatever reason, inevitably in threads on systems languages, someone comes in and postures themselves defensively like this. You might want to reflect on that.
