Re: [boost] [operators] A modern SFINAE-based version of boost::operators?

I am working on a proposal for the next committee meeting that would generate more of these operators. We recently voted in a feature for the comparison operators: the user defines `operator<=>` and gets all current comparison operators generated automatically. I will be sure to post my paper to this list for feedback prior to the mailing deadline. My paper will include a fairly comprehensive rationale for the design, which will be different from Boost.Operators. It has the advantage of needing only to work with code built against the latest standard, and it has language support, and it has the "disadvantage" of being done by default instead of being explicitly requested by the user, which obviously has slightly different design constraints.

Peter Sommerlad, committee member and C++Now presenter who often proposes additions to fill in holes in the standard library, asked me:

Are you aware of anybody who tried to provide a boost::operators style of automatically providing additional operators with a single base class that through SFINAE injects all possible operators based on the ones defined in the template parameter? This won't give you the control of the current boost::operators, but would be much easier to teach.

I'm the current maintainer of Boost.Operators and I heard about anyone working on that.

Above sentence is missing a "haven't": I haven't heard of anyone working on that.
