# The following checks are not used:

# -abseil-* : we are not using abseil
# -bugprone-easily-swappable-parameters : accepting the risk
# -cerl-* : questionable value
# -clang-analyzer-cplusplus.NewDeleteLeaks : due to https://github.com/google/googletest/issues/3553
# -cppcoreguidelines-* : too opinionated
# -google-build-using-namespace : too opinionated
# -google-readability-avoid-underscore-in-googletest-name : impractical, little value
# -google-readability-todo : accepting the risk
# -google-runtime-references : too opinionated
# -misc-no-recursion : not much value
# -misc-non-private-member-variables-in-classes : too restrictive
# -misc-unused-parameters : too restrictive
# -modernize-avoid-c-arrays : too restrictive when writing low level functions and well-defined structures/protocols
# -modernize-use-trailing-return-type : too opinionated, little value
# -readability-function-cognitive-complexity : too noisy on unit tests; clang-13 adds IgnoreMacros which should help
# -readability-identifier-length: impractical
# -readability-magic-numbers : too restrictive when writing low level functions and well-defined structures/protocols
