At this time, this particular node is under consideration for OT. I am thinking this is even not OT.

There is a very subtle difference here. Most of the OT posts are "positive" OT, they are OT because they might cover topics at a level higher than particular language, or might have a coverage wider than particular language. But the thought and the basic principles provided in lots of those OT's are wonderful.

But in this particular case, the post simply has a narrow coverage that has nothing to do with Perl.

Luckily we rarely see this kind of posts.
