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?
