# Disable the following checks due to frequent false positives, noisiness,
# inconsistent style with existing codebase and other reasons:
# -misc-non-private-member-variables-in-classes (potentially too restrictive)
# -misc-unused-parameters (can be cleaned up in batch and enabled)
# -modernize-avoid-c-arrays (too restrictive)
# -modernize-pass-by-value (too restrictive)
# -modernize-return-braced-init-list (inconsistent style)
# -modernize-use-emplace (more subtle behavior)
# -modernize-use-trailing-return-type (inconsistent style)
#
# TODO: enable google-* and readability-* families of checks.
