https://en.cppreference.com/w/cpp/language/lambda
It defines a function named "process_entry" taking one argument (const
value_type &). The body of the function can access variables d and k by
value, and variables new_cfg and offset by reference. I think "this"
might also be captured implicitly in this context, but I'd have to go to
the documentation to refresh my memory.
An alternative to using a lambda would be to move this stuff to a
private member function, or maybe a static function in this file.
