People. Please. Tell me you are *not* arguing over underscores in numeric literals !
This is not totally academic. I have come across the exact bug I describe. It was painful.

So your point is : it is dangerous because it is clearer. I also recommend we forbid comments, since: - they can be abused, even by mistake, to make code *harder* to read - removing them will force people to read code more carefully
Allowing underscores is definitely better than not allowing them, since it makes code clearer. I'd rather put up with the possibility of these bugs than remove the feature altogether. But seeing as we can remove the option for these bugs with a pretty easy-going syntax restriction, why not? (There is no such analogous restriction that would make comments more accurate.)
That being said, I do agree with the general sentiment that too many bytes have been wasted on this thread. I'll try to extricate myself from the debate and get on with something useful :)
