I am imagining something like this
 
{{for (auto&& str : analyzeBSONColumn(binData)) { }}

{{  std::cout << str << std::endl; }}

}
 
Output:
 
{{Simple8b Block: 3 elements }}

{{Interleaved mode start: Reference object: {a: 10, b: 10} }}

{{  Simple8b Block: 3 elements }}

{{  Simple8b Block: 3 elements }}

Interleaved mode end
