func Log(ctx context.Context, level Level, msg string, args ...any) {

// LogAttrs calls [Logger.LogAttrs] on the default logger.
func LogAttrs(ctx context.Context, level Level, msg string, attrs ...Attr) {
	Default().logAttrs(ctx, level, msg, attrs...)

	})
	t.Run("attrs1", func(t *testing.T) {
		wantAllocs(t, 0, func() { dl.LogAttrs(ctx, LevelInfo, "", Int("a", 1)) })
		wantAllocs(t, 0, func() { dl.LogAttrs(ctx, LevelInfo, "", Any("error", io.EOF)) })
	})
	t.Run("attrs3", func(t *testing.T) {
		wantAllocs(t, 0, func() {
			dl.LogAttrs(ctx, LevelInfo, "hello", Int("a", 1), String("b", "two"), Duration("c", time.Second))
		})
	})

without an allocation.

For the most efficient log output, use [Logger.LogAttrs].
It is similar to [Logger.Log] but accepts only Attrs, not alternating
keys and values; this allows it, too, to avoid allocation.

The call

	logger.LogAttrs(ctx, slog.LevelInfo, "hello", slog.Int("count", 3))

is the most efficient way to achieve the same output as

	//
	// A Handler should treat WithGroup as starting a Group of Attrs that ends
	// at the end of the log event. That is,
	//
	//     logger.WithGroup("s").LogAttrs(ctx, level, msg, slog.Int("a", 1), slog.Int("b", 2))
	//
	// should behave like
	//
	//     logger.LogAttrs(ctx, level, msg, slog.Group("s", slog.Int("a", 1), slog.Int("b", 2)))
	//
	// If the name is empty, WithGroup returns the receiver.
	WithGroup(name string) Handler
