Stored Lambda in var

Thanks to Blue Man

int a{};
int b{};
 
auto Blah = [a, &b](int Whatever)
{
  std::cout << a + Whatever << std::endl;
};
 
Blah(20);

Gets compiled as something like

struct SomeCompilerGeneratedName_Lambda
{
  void operator()(int Whatever) const
  {
     std::cout << a + b + Whatever << std::endl;
  }
  
private:
  int a;
  int& b;
};
 
int a{};
int b{};
SomeCompilerGeneratedName_Lambda Blah{a, b};
 
Blah.operator()(20);
