# Exclusions
# - llvmlibc-*
#     Seems very vendor-specific.
# - altera-*
#     FPGA hardware specific.
# - *-default-arguments-calls
#     Often we have to call functions with default arguments.
# - *-braces-around-statements
#     Yes it's bugprone, but conciseness can help readability
# - *-use-trailing-return-type
#     Leading return type is less verbose and more familiar.
# - llvm-header-guard
#     De-facto standard #pragma once is preferred.
# - *-default-arguments-declaration
#     Default arguments are useful.
# - -clion-misra-cpp2023-19-6-1
#     Allow `#pragma once`.
# - llvm-namespace-comment
#     Conflicts with google-readability-namespace-comments, apparently.
