It means your professor is either overly tricky or should think his/her questions through a bit more. In the case of DBI the parens do nothing except take up space and maybe mislead someone.
~>ack \@EXPORT DBI.pm
@EXPORT = (); # we export nothing by default
@EXPORT_OK = qw(%DBI %DBI_methods hash); # also populated by export_ok

the reader .
