# Enable most checks then disable (-) problematics ones:
#
# Some checks are good in principle but cannot be applied automatically either
# because they require taste or the autofix can generate wrong code:
#
# - cppcoreguidelines-pro-type-member-init: wrong code sometimes
# - google-explicit-constructor: libllvm has implicit conversions
# - modernize-use-no-discard
# - modernize-use-transparent-functors
# - modernize-use-using: autofix doesn't handle dependent type templates
# - readability-static-accessed-through-instance: wrong code sometimes
#
# No consensus:
#
# - modernize-use-trailing-return-type: also huge code churn
# - readability-convert-member-functions-to-static
# - readability-implicit-bool-conversion
