PERL's -e check

[Joe Testa <jst3290 () RITVAX ISC RIT EDU>]

Hi all --

        I've noticed here and there that some PERL scripts pass user input
directly into an open() call protected by a "-e" check.  Example:

        # $temp_file is taken from the submitted form
        if(-e $temp_file) {
                open(TEMP, "<$temp_file");
                ...
        }

        Is there any trick that would bypass the "-e"?  Thanks in advance.
