Hello = everyone.

Several weeks ago, I posted a first draft of a proposal whose = goal was to standardize a std::bit_reference.
I've taken into accou= nt the initial comments, and I entirely redesigned the proposal to include = a consistent set of bit tools.
My goal is to have something complete for= the next ISO WG21 mailing.
All critics and comments are welcome, partic= ularly on the design and technical specification part.

Best,

bit_iterator&#= 39;s synopsis seems a little broken:
using= differenc= e_type =3D= intmax_t<= br>
missing semicolon.
using iterator_category =3D typename underlying_iterator :: iterator_category ;
underlying_iterator do= esn't exist elsewhere, and this needs to go through iterator_traits.

Also, the current definition means that=C2=A0bit_ite= rator<const unsigned int *>::reference is bit_reference<unsigned i= nt>, which doesn't seem correct.
