So the parsing complexity might be a wash. If it's not easy to completely resolve the 'le' apparent ambiguity, the extra complexity is trivial: looking ahead 1 or 2 characters in a string that is already accessible. It certainly less complex than adding a new pragma, which you guys were comfortable with.Thread Previous | Thread Next
