Thanks for all the work.
However, I was wondering why you couldn't eliminate some of the
extensive BOOST_PP magic in:
by using the "tagged multiple inheritance"(TMI) method shown
The only disadvantage of TMI that I can think of is that maybe the
template recursion of package_range_c shown at:
suffers some limitation imposed by the template recursion depth.
However, I don't know if that's a real limitation since I have tested
where, if a single template is used in the recursion, then the
-ftemplate-depth-XX seems irrelevant:
The only other objection might be to limit the number of instantiations
because the more template instantiations, the slower the compile
time; however, Doug Gregor suggested he wasn't too worried
about that at the bottom of:
