So, do Boosters think we can actually make a C++ 14 bitfield which:

...

1. Is typesafe, so not a C bitfield.

2. Is convenient for programmers to declare (i.e. little boilerplate in a specific bitfield declaration).

3. Works as you'd expect a bitfield to work, including bitfield::flag.

4. if(bf) works.

5. Is 100% constexpr and generates zero runtime overhead.

This is what I have: http://melpon.org/wandbox/permlink/RDl3B6EmnG5hRuAJ

After re-reading your post, I think this doesn't meet your requirement :p
