On the point of "not possible...", "only a symbol...", etc:T* ptrCast(T, alias ptr)() { return cast(T*)ptr; } void addInt(void* state, void* data) { alias _state = ptrCast!(int, state); alias _data = ptrCast!(int, data); static assert(!is(typeof(_state) == int*)); static assert(!is(typeof(_data) == int*)); *_state += *_data; }
That's a pretty cool workaround, but not an alias to the cast, but an alias to a parametrized function template (a type), so I will stick to my statement of "not possible". AFAIK, this would also invoke the respective function template instance for ptrCast every time _state or _data are referenced, so if we're going with the spirit of the question that's still going to be horrible if the compiler doesn't optimize ;p
