THRUST_UNUSED undefined in thrust::tuple_for_each

[codecircuit]

#include <thrust/detail/tuple_algorithms.h>

#include <tuple>

int main() {
	std::tuple<int, float> t;
	thrust::tuple_for_each(t, [](auto& e){e = 0;});
}

will fail to compile, because THRUST_UNUSED is undefined. I think this macro should prevent compiler warnings about unused variables, but also prevent some unwanted compiler optimizations. You can also search for THRUST_UNUSED in this repository and I only found it once in tuple_for_each_impl. Maybe you meant THRUST_UNUSED_VAR defined in thrust/system/cuda/config.h?
