           Summary: Impossible to cast interface/object reference to void*

struct S
{
}

interface I
{
    @property S foo();
    alias foo this;
}

class A
{
    @property S foo() {  return S(); }
    alias foo this;
}

void main()
{
    A a;
    I i;
    auto ap = cast(void*)a;
    auto ip = cast(void*)i;
}

Error: cannot cast from S to void*

It is easy to workaround for class objects by casting the reference to Object first. Interfaces require more voodoo.

Can we just have a .ptr property on class/interface references?
