But it asserts, do you know why?
I think the problem is that is(T : T*) becomes is(int* : int**)
and that's false.
Then I have written a different program:
[..]
enum bool IsPointer2 = is(typeof(*T)) || is(T == void*);
[..]
Do you know why IsPointer2 is true for the dynamic array type too?
.. no idea.
Curious behavior DArrays exhibit:
void main(){
int[] i = [5,4,3,2,1];
writeln(*i); // prints 5
}
Ick.
