For either static or dynamic

//----
struct S
{
    this(this) @disable;
}

void main()
{
    S s;
    S[1] ss = s; //Passes, should fail
    ss = s;      //Passes, should fail
    ss[] = s;    //Passes, should fail
    ss = ss;     //Correctly fails
    ss[] = ss[]; //Correctly fails
    S s2 = s;    //Correctly fails
}

@safe/pure/nothrow attributes also be ignored wrongly.

struct SA
{
    this(this)
    {
        throw new Exception("BOOM!");
    }
}

void main() pure @safe nothrow
{
    SA    ss;
    SA[1] sa;

    // TOKassign
    ss = ss;    // correctly fails
    sa = ss;    // no error
    sa = sa;    // no error

    // TOKconstruct
    SA    ss2 = ss;     // correctly fails
    SA[1] sa2 = ss;     // no error
    SA[1] sa3 = sa;     // no error
}
