I haven't been able to reproduce this.

I tried:

  template <int> class Foo { void foo(); };
  
  template <int X>
  void Foo<X>::foo() {
      auto m = [this](auto x) {};
      m(42);
  }
  
  Foo<0> a;
  // Foo<1> b;

And I get no hints at all. (Presumably because we only traverse the primary template of `foo`, and Foo<X>::foo()::m::operator() is never instantiated, only Foo<0>::foo()::m::operator() is (with `int`).
