Hi, I'm struggling to understand what's the point of doing the below
... handler = &logHandler{log: log, next: handler} // add logging handler = ensureSessionID(handler) // add session ID handler = &ochttp.Handler{ // add opencensus instrumentation ... Isn't the logHandler struct pointer just thrown away in the next line and so on? If the expressions are evaluated just for their effects and value is to be discarded why just not assign it in the first place? https://github.com/GoogleCloudPlatform/microservices-demo/blob/ccff406cdcd3e043b432fe99b4038d1b4699c702/src/frontend/main.go#L147 -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
