	h := slog.NewJSONHandler(os.Stderr, &slog.HandlerOptions{Level: programLevel})
	slog.SetDefault(slog.New(h))

Now the program can change its logging level with a single statement:

	programLevel.Set(slog.LevelDebug)

# Groups

Attributes can be collected into groups.
A group has a name that is used to qualify the names of its attributes.
How this qualification is displayed depends on the handler.
