Not that I'm advocating this, but one could just include the entire set
of Boost libraries all at once in a regression test to detect
conflicting definitions. Personally, I think the boost namespace is too
full already. In header declarations, you can't have using boost::abc,
so you end up qualifying everything as with boost::abc::xyz which is
really tedious and only "special" libraries get a plain boost::xyz. I'd
rather just have abc::xyz which I think results in better
modularization. In that sense, aside from a community and vetting
process, Boost becomes a library distribution mechanism rather than a
supposedly coherent framework.
