Okay, I must admit that I have not read the perldoc files for these functions for v5.6.1, but in the v5.6.0 perldoc entries it did not go into the semantic differences between these items.

So what exactly do each of these do different? What instances would I use either one? Is there an FAQ, article, or literary material somewhere I should look at?
