Quick question about doing this: would it be more cost effective to use a std::multimap to allow iterating through the namespaces in ascending order of NNS length and exiting the loop once NNS length + edit distance are worse than the best, or to use an llvm::SmallVector instead and always looping over all of the namespaces, but skipping the lookup if (NNS length + ED) is too long?</blockquote>
