how do I cast a `pointer` (btw, what is this? a MLIR type?) to a `Pointer` or preferably a `DTypePointer`? Inspired by [this](https://github.com/modularml/mojo/blob/main/examples/notebooks/RayTracing.ipynb) code, ```py out_arr.data = DTypePointer[dtype]( __mlir_op.`pop.index_to_pointer`[ _type : __mlir_type[`!kgen.pointer<scalar<f32>>`] ]( SIMD[DType.index, 1]( in_arr_f32.__array_interface__["data"][0].__index__() ).value ) ) ``` (where `in_arr_f32` is a numpy ndarray) but I get ``` Included from /home/prj/mojo/mojo-array/test.mojo:3: /home/prj/mojo/array2d.mojo:784:44: error: cannot construct 'DTypePointer[dtype]' from 'pointer<scalar<f32>>' value in assignment out_arr.data = DTypePointer[dtype]( ~~~~~~~~~~~~~~~~~~~^ /root/.modular/pkg/packages.modular.com_mojo/bin/mojo: error: failed to parse the provided Mojo ``` should be fine according to [docs](https://docs.modular.com/mojo/stdlib/memory/unsafe.html#init__-1)?
