I don't think many frown upon the Yi developers for it: http://yi-editor.github.io/2014/09/05/oop/ http://yi-editor.github.io/2014/09/05/oop/ > That is, until you actually do it; I don't think I ever saw people complaining about any actual instance of OOP-like code, just about the idea. Sometimes there is something to complain about ;) I remember listening to a Haskell Cast with Michael Snoyman and/or Gabriel Gonzalez of the Conduit and Pipes fame... whoever it was mentioned that their early designs were very imperative because they thought it was necessary for performance. However over time a functional API/core emerged and was more stable and performant.
