--- Comment #8 from Paolo Carlini <paolo.carlini at oracle dot com> 2013-01-01 22:24:03 UTC --- I don't have much to say, the patch is still awaiting approval. Frankly, I don't personally consider the issue very serious and definitely isn't a regression, at this point we could as well leave the lexer alone for 4.8.
