The Lexical Workflow solution

Here's our entire ProcessCar workflow:

func ProcessCar(lineBase64 string) (err error, carJson string) {   step := Get(lineBase64)   step = Next(step, Base64ToBytes)   step = Next(step, BytesToData)   step = Next(step, TimestampData)   step = Next(step, DataToJson)   json, err := step(nil)   if err != nil {      Error.Error(err)   } else {      carJson = json.(string)   }   return}

How's that for clarity? Each step one after the next and error handling at the very end.

This Go idiomatic Monadic workflow solution needs a label, and because I thought of it first, its name is The Lexical Workflow. It's how we can do Monadic composition of impure components in Go. Lex means law, and since it controls and rules over our workflow, the name fits. ...
