--- Comment #2 from Luke Dalessandro <ldalessandro at gmail dot com> ---
It's also possible to workaround this with array allocation.
```
struct Foo {
constexpr virtual ~Foo() {}
};
constexpr bool foo() {
Foo *ptr = new Foo[1]{};
delete [] ptr;
return true;
}
static_assert(foo());
```
Obviously both of the workarounds require that we be able to cast from a `Foo*`
to our derived pointer, at which point we might as well skip the virtual
destructor and add an abstract `virtual void destroy() = 0` member where we can
just call `delete this` anyway.
