More succinct of way of doing it:

all_headers = dict(item for sublist in include_state.include_list
                   for item in sublist)
bad_headers = set('%s.h' % name[:-6] for name in all_headers.keys()
                  if name.endswith('-inl.h'))
bad_headers &= set(all_headers.keys())  # compute intersection

for name in bad_headers:
  # lineno = all_headers[name]

It's also slightly more idiomatic vis-a-vis other include checks.

@bnoordhuis okay, will try this. That said, I'm more interested at this point to find out what's wrong with my solution? It might not be idiomatic, but it should work. Why does error not work?

Oh, is that your question? :-)

I assume you're testing it from the command line like this: python tools/cpplint.py src/*.cc?

Look for _DEFAULT_FILTERS: build/include is off by default. Pass --filter=build/include to test it, or --filter=+build/include to enable it in addition to the other rules.
