void is not a value but a type.
intSet[6] = void; <--- seems you want to assign void to intSet[6]?

alias void[int] IntSet;
void makeVoid(){}
void main(){
  IntSet intSet;
  intSet[6] = makeVoid();
  intSet.remove(6);
}

But this one also does not work.

There should be a way to insert a key to void[int].

I think that the bug is that void arrays are permitted at all. What exactly is
an array of nothings? And if you had one, does it take up any memory.

If what you are asking for is a set of hashed keys, then use...

   bool[int] 
or
   byte[int]

At least these mean something.

What exactly are you expecting to be able to set a void to?
