Yes, in fact I use the first one (while true; sleep; ls) but I thought the second is more succint. Anyone interested can make a loop. Please notice that most of the snippets aren't meant to be copied & pasted, but rather analyzed and understood by the user.
Ah, sometimes that's a hard line to draw since often the people that know enough to understand not to take it literally don't really need the pointer in the first place. :)
