I wonder if the overhead of using context values is noticeable in the context of logging. I guess you want to reconstruct the logger only when needed, kind of lazily

It might be noticeable at extreme levels, which I've never come anywhere to noticing.

I tend to only use `log := clog.FromContext(ctx)` once at the top of a method, and not `clog.InfoContext(ctx, "...")`, but that's mostly for style reasons and not performance.

Who’s up for a micro-benchmark? Jk, will definitely consider it
