func getVaList(_: [CVarArg]) Returns a CVaListPointer built from args that's backed by autoreleased storage. Warning: This function is best avoided in favor of withVaList, but occasionally (i.e. in a class initializer) you may find that the language rules don't allow you to use withVaList as intended.
