Is my understating correct for use "CGI qw(:standard)" vs. "use CGI"?

I'm using the function "redirect('http://www.example.com')" in my script. When I use "use CGI" instead of "use CGI qw(:standard);" I get the following error:
Software error:
Undefined subroutine &main::redirect called at upload.pl line 109, <fh
+00001C%3A\Program Files\Java\j2re1.4.2_06\javaws\javalogo52x88.gif> l
+ine 20.

For help, please send mail to the webmaster (webmaster@example.com), g
+iving this error message and the time and date of the error.

When I use use "use CGI qw(:standard);" the function works.

My understanding is that "use CGI" is for Object Oriented programming. And "use CGI qw(:standard);" is for Function Oriented programming.

Using "use CGI" I'd have to do:
use CGI;
my $q = new CGI;
$q->redirect('http://www.example.com')

Using "use CGI qw(:standard); " I'm importing the function for Function Oriented programming.

use CGI qw(:standard);
redirect('http://www.example.com');
