Why doesn't evalf work on the data structures below?
 

M1 := Matrix([[m__1, m__2]])

Matrix(%id = 36893488151929448556)

 (1)

M := [M1, M1]

[Matrix(%id = 36893488151929448556), Matrix(%id = 36893488151929448556)]

 (2)

m__1 := 1; m__2 := 2

M

[Matrix(%id = 36893488151929448556), Matrix(%id = 36893488151929448556)]

 (3)

evalf(M)

[Matrix(%id = 36893488151929440844), Matrix(%id = 36893488151929440964)]

 (4)

evalf(M[1])

Matrix(%id = 36893488151929437108)

 (5)

evalf(op(M))

Matrix(%id = 36893488151929432292), Matrix(%id = 36893488151929432412)

 (6)

evalf(op(M[1]))

1., 2., {(1., 1.) = m__1, (1., 2.) = m__2}, datatype = anything, storage = rectangular, order = Fortran_order, shape = []

 (7)

NULL
