By the way---not suggesting to touch the document, of course, but just for the record---it _is_ convenient to have the escape character act uniformly on any character, even if it has no special meaning. For example (it is a rare case, but I have encountered it), when generating literal strings programmatically and not having a way to determine what character is inserted in the generated value, it is convenient to simply precede the unknown character with the escape character and rest assured that the string literal will always be well-formed. Just my 0.01999..., of course. ---Vassil. -- Vassil Nikolov | Васил Николов | <[email protected]> "Be careful how you fix what you don't understand."
