device/host function with the same name

[fwinter]

Is it somehow possible to define different implementation for the host and the device function?
nvcc keeps complaining about invalid redeclaration of member function “A::foo()”.

struct A {
device void foo() {
// implementation device
}
host void foo() {
// implementation host
}
};

If disallowing same names on the device and the host is a good design feature could someone explain why this would be good to have?

struct A {

    __host__ __device__ void foo()

    {

#ifdef __CUDA_ARCH__

        // device implementation

#else

        // host implementation

#endif

    }

};
