I think the two first are unnecessary (could you try this out? thx)
Actually none of them are necessary. Ah the wonder of templates :-)
Wonderful they are, you're right :) So, I guess this is as good as it can get. Slightly OT: this issue of POI could be taken a little further to allow interoperability between (not necessarily template-based) libraries without the headache of having to include portions of them. This is what I have in mind: suppose a header-based library A provides support for or somehow uses a non-header (i.e. requires linking) library B, like this: // lib A #include <b.hpp> inline foo(){...} // does not depend on B inline bar(){...} // does not depend on B inline mess_with_B(){...} Now, if B is not linked in the project mess_with_B won't compile, so one has to move this function to a separate header that the user will/won't include depending of whether she wishes that functionality. Instead, one can do the following: // lib A #include <b.hpp> inline foo(){...} inline bar(){...} template<typename dummy> inline mess_with_B(dummy* =0){...} Voila, A works even if B is not linked in. If the user has linked B and wants to use mess_with_B, then she just has to call mess_with_B() as usual, template instantiation model will do the rest. Maybe I'm missing something, but I think this approach could be investigated a little further. One good example of use is for interoperability with Boost.Threads, for instance. Totally OT: I've posted a question regarding multi_index and composite keys a few posts ago. You being one of the reviewers, your opinion on that is greatly appreciated :) Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

Interesting...yep that probably works. Makes you need to rethink what dependency means...

I haven't been able to get around to reading the thread -- I'll try to get to it later... Jeff
