What version of the compiler are you using?

Ahh, the struct needs to be in a unittest block for it to happen:

struct R
{
    @disable this(this);
    int* _ptr;
}
unittest
{
    struct S
    {
        @disable this(this);
        int* _ptr;
    }
    struct T
    {
        int* _ptr;
    }
    pragma(msg, "R: ", typeof(R.tupleof));
    pragma(msg, "S: ", typeof(S.tupleof));
    pragma(msg, "T: ", typeof(T.tupleof));
}

prints

R: (int*)
S: (int*, void*)
T: (int*)

Why is that?
