--- Comment #2 from Luke Dalessandro <ldalessandro at gmail dot com> ---
Is this demonstrating the same behavior, and is clang wrong to accept?
```
template <class T, int = 1>
struct Foo
{
Foo() = default;
Foo(Foo const&) = delete;
template <int I>
Foo(Foo<T, I> const&) {}
};
template <class T, int I>
Foo(Foo<T,I>) -> Foo<T,I+1>;
Foo<int> a;
Foo b = a;
```
