First, you've purposefully picked the smallest module that you could find. And can you back up your claim that "the same people who shame other people's work worship and publish one-line modules"? Can't you see how using terms like "shame" and "worship", which poor Blake never used no accused anyone of, is inflammatory?

Second, so what? So it's alright to copy and paste the function? It is alright if a coworker wrote the function and presented you with an interface? Would you have a problem if a single module that was "designed in isolation, documented in isolation and can be used in isolation" but was published internally?
