If you were paying close attention as you went through the blog post on the root loop you may have noticed a little slight of hand.  I may have been stung, but I'm not sure.

In the central coastline deserts of Chile there exists an elusive wingless wasp that looks like a panda bear, is referred to as an ant, and has a sting strong enough to put a cow down.
Meet the Panda Ant:

Similarly, deep within LabVIEW there exists an elusive message loop that has the potential to sting you.  The Panda Ant is neither good (its sting can paralyze a cow) nor bad (it looks like a panda bear), but learning about it now will prevent you from getting stung by it in the future.  The same can be said for the root loop, it's not a bug in LabVIEW and you have most likely never noticed that it exists, but learning about it now could prevent you from getting stung by it in the future.
