It looks to me like the barb "flip" is for something else entirely--it 
is a right-hand versus left-hand sort of flip.  This would be 
inappropriate for quiver, which makes symmetric arrows.  I would 
strongly oppose any proposal for a kwarg to reverse the direction of the 
arrows.

All the data continuously generated in your IT infrastructure contains a
definitive record of customers, application performance, security
threats, fraudulent activity and more. Splunk takes this data and makes
sense of it. Business sense. IT sense. Common sense.
