I had a similar reaction to that, glad it's not just me.

Meanwhile with the 4th item, this whole example is gross, repeatedly polling a buffer every 100ms is a massive red flag. And as for the data race in that item, the idiomatic fix is to just use io.Pipe, which solves the entire problem far more cleanly than inventing a SyncWriter.

The author's last comment regarding "It would also be nice if more types have a 'sync' version, e.g. SyncWriter, SyncReader, etc" probably indicates there's some fundamental confusion here about idiomatic Go.
