Well, i am at a very beginner level with Flex. I could see how flex works with it even if it is a ambiguity. Since it
matchesthe rule with the maximum text and we don't allow a new line character in the rule, it works fine. Even in
LL(1),it works fine, but throws warnings. So i just thought of suggesting to remove the ambiguity.<br /> But do we need
toallow comments as part of unicode escapes?<br /><br />Thanks,<br />Gokul.<br /><br /><div class="gmail_quote">On Wed,
