I haven't investigated if there are more occurrences or if it's worth enforcing turning the check on generally. (They were flagged on the Google roll, ironically) --- [`readability-redundant-smartptr-get`](https://clang.llvm.org/extra/clang-tidy/checks/readability/redundant-smartptr-get.html) > Find and remove redundant calls to smart pointer’s `.get()` method [`performance-for-range-copy`](https://clang.llvm.org/extra/clang-tidy/checks/performance/for-range-copy.html) > Finds C++11 for ranges where the loop variable is copied in each iteration but it would suffice to obtain it by reference.
