We still need to define how a `static` device variable should be visible on the host side. How that behaves in the context of relocatable code generation as well as anonymous namespaces. Also, in the context of CUDA runtime/driver API, if a device variable is addressable on the host side through the runtime API, it should be addressable through the driver API as well. However, the naming will be a big challenge.
