Very simple bitset operations in JavaScript
/* bitset.js
*
* bitset = new Bitset(64);
* bitset.toString(); // "0000000000000000000000000000000000000000000000000000000000000000"
* bitset.setBit(48, 1).setBit(23, 1).setBit(52, 1);
* bitset.toString(); // "0000000000010001000000000000000000000000100000000000000000000000"
* bitset.toInt(); // 4785074612469760

Playing with C++11. Inspired by https://github.com/klmr/named-operator
#include <iostream>

inline func_t operator > (lhs_t const &lhs, func_t rhs) {
return rhs;
