I think that and the previous issue go hand in hand, contributing to each other: > Unfortunately, C++ Libraries are often not designed for interoperability with other libraries And I think it's not just that the libraries don't work well with each other, but they also only work with a subset of C++ projects since any given group of collaborating C++ programmers seems to settle on their own subset of the language to allow in their coding standards. Perhaps I am falling into the trap of thinking about old C++ now -- modern C++ does seem to have more of a broadly understood idiomatic style.
