Con la versión 0.10.0 (#19 ) los métodos ToString() usan monads.
Ejemplo:

public override string ToString() =>             
            string.Create(11, this.Componentes,
                (span, value) =>
                    {
                        var x = value.Tipo.AsSpan();
                        var y = value.NumeroDeDocumento.AsSpan();
                        var z = value.Verificador.AsSpan();
                        span[0] = x[0];
                        span[1] = x[1];
                        span[2] = y[0];
                        span[3] = y[1];
                        span[4] = y[2];
                        span[5] = y[3];
                        span[6] = y[4];
                        span[7] = y[5];
                        span[8] = y[6];
                        span[9] = y[7];
                        span[10] = z[0];
                    });

Resultando ser mas rápido que la versión previa:

Con la versión 0.10.1 (#21) se reduce al minimo el uso de variables en cálculo del método CalcularVerificador.

private static byte CalcularVerificador(string cadena) {
            ReadOnlySpan<char> _cadenaSpan = cadena.AsSpan();
            return Convert.ToByte((
                (6 * byte.Parse(_cadenaSpan.Slice((0), 1))) +
                (7 * byte.Parse(_cadenaSpan.Slice((1), 1))) +
                (8 * byte.Parse(_cadenaSpan.Slice((2), 1))) +
                (9 * byte.Parse(_cadenaSpan.Slice((3), 1))) +
                (4 * byte.Parse(_cadenaSpan.Slice((4), 1))) +
                (5 * byte.Parse(_cadenaSpan.Slice((5), 1))) +
                (6 * byte.Parse(_cadenaSpan.Slice((6), 1))) +
                (7 * byte.Parse(_cadenaSpan.Slice((7), 1))) +
                (8 * byte.Parse(_cadenaSpan.Slice((8), 1))) +
                (9 * byte.Parse(_cadenaSpan.Slice((9), 1)))
                ) % 11);
        }
