I think this is another case where the fact that you can't get a person's tone of voice via text causes people to take things the wrong way.

As another person said of themselves, I like the fact that people on HN point to other tools they use in a way that is related to the one being discussed in the comments. That makes HN a good place to find out about tools you hadn't heard of.

I didn't think the original comment was intended to be dismissive of zuo, but they were just pointing out their preference for a tool in that vein (which made sense to me since both are lisp-ish languages made for shell scripting).
