Since a destructor ignores `const`, I think adding the `~this`
to Foo manually is somehow making the compiler have to actually
cast away const, which it is doing via `cast(Foo) foo`, which
fails since you've declared your own `opCast` that only accepts
arguments implicitly convertible to `bool`.
I say this because removing the specialisation in `opCast` and
changing the return type of it to `Foo` works :
```d
struct Foo{
Foo opCast(T)()const {
assert(0);
return this;
}
~this() {}
}
struct Bar{
const Foo foo;
}
void main(){
//Bar bar = Bar(); //this will trigger the assertion failure
}
```
Thanks, you are right, generated Bar.~this() try use opCast to
cast const away.
Is look like bug in compiler.
I stop using opCast for now.
