   The following fast-path can be addressed in the TVM FFI:
   - ```tuple```, ```list``` via translation in python/cython side (see benchmark above)
   - ```str``` is already fast (seem benchmark above)
   - ```Context``` can be quite fast if the object is a tvm object, around same mangitude as passing NDArray
   - ```np.dtype``` can get around by by str conversion, or introduce a type structure, TVM FFI support DLDataType natively
   - None: natively supported by FFI
   
   The following items needs to be discussed
   - py_slice, Ellipsis Can be supported by adding pyobject support, however that introduces dispatching into the FFI layer(making the function not accessible to other language frontends). Would be interesting to discuss alternatives
