There's a bug right now and the parser won't handle CPP Multiline comments not separated by whitespace. We'll update the pull request when a fix has been pushed and include a test to cover this case.
/*HELLO*//*WORLD*/
Just noting that, I have internally resolved the conflict which occurred with a38c32c66a8b3e920e7fe0d13d1d3b3879a67f88 change, so don't worry about rebasing this PR :D.
