Subject: Disambiguate between C++11 lambda expressions and C99 array
 designators in the parser. In the worst case, this disambiguation requires
 tentative parsing just past the closing ']', but for most cases we'll be able
 to tell by looking ahead just one token (without going into the heavyweight
 tentative parsing machinery).
