I'm trying to initialize a `std::bitset<256>` at compile time with some of its indices, lets say 50-75 and 200-225 set to 1.

Based on <http://en.cppreference.com/w/cpp/utility/bitset/bitset>
It looks like my 2 options are:

```
constexpr bitset();
constexpr bitset( unsigned long long val ); 

```

Could someone shed light on how I would initialize my bitset considering the second constructor wouldn't work for large indices?
