I'd like the code complete approach. A method has 4 channels: api, status, input, output. Reducing how many channels interact semplify code a lot. Oop went for input, status and statu, output pairs. Functional uses input, output and api, output pairs. Good programmers understand that and apply the one which is proper to model their problem, to reach performance/memory goals and most importantly to reduce te cognitive load of large codebases.
