From @StanLepunK in processing#5753,

Ciao Sam few word about PVector, I read there an idea to change PVector class for Processing 4 https://github.com/processing/processing/wiki/Processing-4#other-nuts-and-bolts . Few time ago i propose do @benfry to work it, if he want on my Vector class to design it specificly to Processing https://github.com/StanLepunK/Rope/tree/master/src/rope/vector
Maybe with your branch may be if Ben and the Processing Staff is ok, I can work on it to merge with your branch ? Let me-us know, if you're interested.

What are people's thoughts?
