In C and C++, void* is for data pointers only. As function pointers are
a different kind of beast, casting to and from void* is undefined
behavior. (Note: It works on all common platforms.)
Wow, really? That is strange.
I wonder whether D has any decision on that.
I would hope it's defined. A pointer is a pointer.
