# Precise and Flat Reflection (ex Magic Get, ex PODs Flat Reflection)
This C++14 library is meant for accessing structure elements by index and providing other std::tuple like methods for user defined types.
This C++14 library is meant for accessing structure elements by index and providing other std::tuple like methods for user defined types without any macro or boilerplate code.

### Motivating Example #0
```c++
// requires: C++14
#include <iostream>
#include <string>
#include "boost/pfr.hpp"
struct some_person {
std::string name;
unsigned birth_year;
};
int main() {
some_person val{"Edgar Allan Poe", 1809};
std::cout << boost::pfr::get<0>(val)
<< " was born in " << boost::pfr::get<1>(val);
}
```
Outputs:
```
Edgar Allan Poe was born in 1809
```
