Comment (by daniel_frey):

 Thanks for the report, but I think the problem is a bit larger than that.
 I started working on a successor for Boost.Operators which has explicit
 versions for commutative and non-commutative operators (for where is makes
 sense). This library also takes advantage of rvalue references, thus
 eliminating superfluous temporaries. If your compiler has support for
 rvalue references and this would be an option for you, have a look at
 https://github.com/d-frey/operators/. With rvalue references, there are
 additional optimization opportunities if the operator in question is
 indeed commutative, so yes, that property just got a priority bump.

 Any feedback on the library is welcome. I'll also post an announcement of
 this library on the Boost list shortly, with any luck (and probably some
 more work), I hope that this can become the base for Boost.Operators v2.

 If this is not a viable solution for you, please let me know.
