Just create c++ file and enter:

#include <vector>
#include <algorithm>

int main()
{
    std::vector<int> v;
    std::for_each(v.begin(), v.end(),
                  [](int i) {
                      switch (i) {
                      case 1:
                          break; // (1) ok: syntactic symbol is statement-case-intro
                      }
                  });
    auto fn = [](int i) {
        switch (i) {
        case 1:
        break;  // (2) wrong: syntactic symbol is brace-list-entry
        }
    };

    [](int i) {
        switch (i) {
        case 1:
            break; // (3) ok: syntactic symbol is statement-case-intro
        }
    };
    return 0;
}

So, while (1) and (3) are parsed fine, (2) is parsed in a wrong way.
