<p>
<div>
<pre>The following code should be rejected as no matching declaration found as
GCC/MSVC++ does. clang-13 incorrectly passes without considering that two
lambda expressions are never considered as equivalent.
[temp.over.link#5.sentence-4]
1.
template <class T>
struct A{
void spam(decltype([]{}) );
};
template<class T>
void A<T>::spam(decltype([]{}))
{}
2.
struct A{
template <class T>
void spam(decltype([]{}) );
};
template<class T>
void A::spam(decltype([]{}))
{}
Both of above should be rejected as no declaration found.</pre>
