The issue as described by the original poster was that the code was not executed but displayed. They read it and understood how it works. This set them on a trajectory to try it themselves.

But without some tangible harm I don't see why we're supposed to disapprove of it. Maybe allow some hacker spirit while posting on Hacker News :-)
