Sorry, I've missed a beat somewhere. "Arrowized?" What's this bit with arrows?

I saw the term arrow earlier and I think I've assumed that it was some slang 
for the FRP thing (if you think about it, that makes some sense.) But starting 
with intuitive assumptions is usually a bad plan, so I'd love some 
clarification if possible.
