This seems to be in line with our current behavior, so I hope it's right:

  struct S { S(int); };
  
  template<typename T>
  auto l = [](T x = T()) { return x; };
  
  template<typename T>
  struct Fun {
      T operator()(T x = T()) const { return x; }
  };
  
  void f() {
      l<int>();   // Ok.
      l<S>(S(0)); // Error at "T()": no matching constructor for initialization of 'S'
      Fun<S> f;
      f(S(0));    // Ok.
  }
