"Modules is, in my opinion, one of the most sorely needed features in C++. They have the potential of increasing compile times by an order of magnitude or more, thus bringing compile-time performance more in line with more modern languages, ..." Presumably that should be "decreasing", not "increasing" (or "compilation speed" rather than "compile times").
