Perhaps I'm too late to influence anything, but during my talk at BoostCon, Rob Stewart brought this thread up as it relates to my Generic library. The truth is, I've sort of purposely been staying away from the thread until now because I loathe these types of discussions, but I suppose that I should at least poke my head in and voice my opinion. That said, I hate to make things more complicated, but I faced this operator naming problem when making my Generic library and I used the names specified in N2914 (the last working paper that had concepts), only I converted everything to all lower-case with underscores for spaces. This is similar to what Dave suggested here: On Tue, Mar 29, 2011 at 8:11 AM, Dave Abrahams <dave@boostpro.com> wrote:
The C++ standard proposal for concepts used HasXXX (e.g. HasRightShift) for such syntactic tests (see http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2008/n2502.pdf). I think the word "_operator_" doesn't add much here.
If anyone wants to see all of the operator names that I used in one place, as based on N2914, see slide 67 of my talk: https://github.com/boostcon/2011_presentations/raw/master/thu/Boost.Generic.... The only ones on that table that don't come directly from N2914 are the ones that didn't have an associated "HasXXX" concept, which are, iirc, -> ->* new new[] delete delete[] For the above few operators I just picked names that made the most sense to me and I doubt there is much controversy with respect to them anyway. The operator() concept also used a different concept name in N2914 (it's not HasCall, it's Callable), and so I settled on simply "call". As I mentioned, there was a very brief discussion of this thread and my rationale during the talk, so I'll link that whenever the video becomes available. In short, given that these names were all listed in the last working paper which had concepts, I'd say that they are the closest thing that we have to a complete and consistent set of operator names in the standard. At the very least, I present the above list as a reference for the names that C++0x concepts would have used had they not been cut. -- -Matt Calabrese
