I work intensively with c++ 11. Currently sublime 3 does not support raw literals, i.e. the syntax highlighting is absolutely broken when I use R"(...)" notation.
It could be very helpful if you could add at least partial support for raw literals, i.e, not for every delimiter but only for R"( . See http://en.wikipedia.org/wiki/C%2B%2B11# ... g_literals for more information about c++ 11 new string literals.
