I think it would be difficult to identify problematic C++ keywords usage
from patches because headers can legally contain C++ keywords and
checkpatch.pl doesn't know where it should be used.
Do you have any good ideas?

And, at least for QAPI, scripts/qapi.py automatically detects the
keywords to add q_ prefix for them (like `q_class' in this patch).
