   Next on my TODO list (after lfortran/lfortran#1210).

   numpy.size() has already been completed in this #1777 .

   Also shape()

   I can try to add this. But for shape we would need another intrinsic like ArrayShape right?

   Use the Shape IntrinsicArrayFunction. Here is how LFortran does it:

   integer(8) :: x(2, 2)
   print*, shape(x)
   end

   It gives:

                       [(Print
                           [(IntrinsicArrayFunction
