#### Disabled checks and why: #####
#
# -bugprone-too-small-loop-variable,
#     Complains about uint8_t or uint16_t when the limit on the loop is a container's .size() (size_t).
#     We usually do this when we know the maximum size of the container though, so propose leaving disabled.
# -clang-analyzer-cplusplus.NewDelete,
#     Seems to generate false positives. Suggest relying on ASAN and valgrind for memory stuff.
# -clang-analyzer-cplusplus.NewDeleteLeaks,
#     Seems to generate false positives. Suggest relying on ASAN and valgrind for memory stuff.
# -modernize-use-nodiscard,
#     New C++17 feature, slightly polarizing. Would clutter codebase.
# -modernize-avoid-c-arrays,
#     We use C-style arrays in page.h, type.h and logger.h. They're a little more ergonomic than std::array. Thoughts?
# -readability-magic-numbers,
#     Let's not deal with people doing ridiculous things to hack around this. If it bites them, it bites them.
# -bugprone-branch-clone, -bugprone-signed-char-misuse, -bugprone-unhandled-self-assignment,
# -clang-diagnostic-implicit-int-float-conversion, -modernize-use-auto, -modernize-use-trailing-return-type,
# -readability-convert-member-functions-to-static, -readability-make-member-function-const, -readability-qualified-auto,
# -readability-redundant-access-specifiers
#    Not available on clang-8. Disable for forward compatibility with students running modern clang versions.
