Happy to remove it if we wish, it was to maintain consistency with the rest of the CUDA support below (e.g. memmove) when we added the other bits and pieces, @vzakhari may know better if this is a reasonable addition or not or you of course might as well :-) so please do advise if either of you wish it removed or altered, happy to do so!
