Can the ternary conditional even be used to assign objects of the 
wrong type?

dcondo.d

import std.stdio;

class A {
    int a;
    this (int i)
    {
       a = i;
    }
}

class C {
    int c;
    this (int i)
    {
       c = i;
    }
}

void dump (A a, A b, C c, C d)
{
    a.writeln;
    b.writeln;
    c.writeln;
    d.writeln;
    a.a.writeln;
    b.a.writeln;
    c.c.writeln;
    d.c.writeln;
}

void main ()
{
    A a = new A (1), b = new A (2);
    C c = new C (3), d = new C (4);
    dump (a, b, c, d);
    true ? a = b : c = d;
//   a = c; // Error: cannot implicitly convert expression
//   c = a; // Error: cannot implicitly convert expression
    dump (a, b, c, d);
}
