As a classic bit operation utility in C++, std::bitset has always been recommended for bit storage representation.

Although it lacks begin()/end() member, its interface still looks like a container to me. I'm curious if there has been a proposal to turn it into a C++20 range?

If so, this means that it could interact well with the large number of range utilities introduced in C++20, such as:

  bitset<30> b{...};
  auto r = b | views::drop_while([](bool b) { return !b; });

which seems reasonable to me.

Is this an enhancement worth considering, or is it a bad idea?
