The behavior of exists() with strings is different. The more, there's difference across data types but not across the situations. Is this a bug or I missed something from the help?

With strings, we have to be careful with the notorious use/mention distinction (that is, "s" as string literal versus 's' as the name of a string) and that was not done right for exists(). P.S. Oleh, any chance of your using a mail program that respects line breaks, so that I and others don't have to download and edit your mails before we can figure out what the heck you're talking about?
