How about adding the new data structure bitmasks, as the bitset in stl of c++

[Nimit Bhardwaj]

I once worked with the bitset of c++ its quite handy sometimes when you do competitive coding and is also useful for the works regarding OS studies. So I think it should be implemented

[Srđan Panić]

Sounds like a good idea.
