## NAME
    [CGI::Session::ErrorHandler] - error handling routines for [CGI::Session]

## SYNOPSIS
        require [CGI::Session::ErrorHandler];
        @ISA = qw( [CGI::Session::ErrorHandler] );

        sub some_method {
            my $self = shift;
            unless (  $some_condition ) {
                return $self->set_error("some_method(): \$some_condition isn't met");
            }
        }

## DESCRIPTION
    [CGI::Session::ErrorHandler] provides set_error() and errstr() methods for
    setting and accessing error messages from within [CGI::Session]'s
    components. This method should be used by driver developers for
    providing [CGI::Session]-standard error handling routines for their code

  METHODS
    set_error($message)
        Implicitly defines $[pkg_name::errstr] and sets its value to $message.
        Return value is always undef.

    errstr()
        Returns whatever value was set by the most recent call to
        set_error(). If no message as has been set yet, the empty string is
        returned so the message can still concatenate without a warning.
