Isn't this a C++14 feature?

the following simple example compiles for me with std=c++14 or std=c++17 but 
fails with std=c++11 or std=gnu++11 :

int main ()
{
  auto f = [] (auto x) { return x + 1; };
  f (1.0);
}


$ clang++ -std=gnu++11 pippo.cc -o pippo
pippo.cc:3:16: error: 'auto' not allowed in lambda parameter
  auto f = [] (auto x) { return x + 1; };
               ^~~~
