That said, there is an ongoing discussion on which C++ features we<br>
should actually use in LLVM/Clang. At the end of the day, not<br>
everyone who contributes to LLVM/Clang is a C++ guru, and using<br>
esoteric C++ features may actually be more of a detriment than a<br>
blessing as it may scare off potential contributors. So when we look<br>
at whether or not to pull in library X or language feature Y into the<br>
code base, we need to consider the tradeoffs both in terms of<br>
technical benefits (which may be marginal) versus (a) the<br>
approachability and readability of the code base and (b) the<br>
portability of the code base. We aren't luddites, however, as we do<br>
indeed use some of the more "specialized" features of C++ in LLVM/<br>
Clang, but they are buried deep in the code and help provide<br>
fundamental infrastructure instead of being used as part of the basic<br>
APIs.<br>
