Okay, so far so good
int[] a = cast(int[]) cast(void*) l;
Umm, you haven't specified a length? int[] a = (cast(int*)l)[0 .. 3];If the callback is being called (in effect under the current stack frame and won't escape), I would wrap the data you need in a struct and pass that to it instead by pointer. No need for heap allocation and gives a way to pass more complex data should the need arise.
