[go-nuts] Re: [RFC] Yet another proposal for Go2 error handling

Repeating Justin's consideration: one of my (and from colleagues I discuss the topic with) major issues with current error handling is the repetition of identical code. Your proposal still requires `when err handle ...` at every statement. It also doesn't allow for nested call of functions that

[go-nuts] Re: glog: how to add wrapper to log sinks ? Maybe move glog/internal/logsync out of internal ?

A bit more of search and I found klog <https://pkg.go.dev/k8s.io/klog/v2>, which conveniently already provides SetLogFilter <https://pkg.go.dev/k8s.io/klog/v2#SetLogFilter>, which resolves the issue. cheers Jan ps.: s/logsync/logsink -- sorry. On Monday, May 22, 2023 at 7:30:11

it is marked as `internal`, so not accessible. Any chances it could be made public ? Or any suggestions on how to easily achieve the same result ? Thanks! Jan ps.: I looked at other logging libraries, but I do require (use often) fine-grained level control of logging per file, like glog
