I'm afraid there isn't really a way around the explicit cast, at least for now. The documentation [1] says that memcpy_dtoh only takes int or DeviceAllocation objects. If you have Boost.Python code that you are compiling, you can mimic what PyCUDA does for DeviceAllocation. It is also possible to have PyCUDA attempt a __long__ cast wherever it takes a device pointer--do you think it's imperative that this should be done?
