Why should I create an object?

[Greenhalgh David]

Bare in mind that I am still a beginner at coding. Why is it "good 
practice" to create an object when using CGI, rather than just diving 
in?

For example:

use CGI ':standard';
my $q=new CGI;
my $input=$q->param('input');
and

use CGI ':standard';
my $input=param('input');
both put the contents of 'input' into $input and the last one has less 
lines and less opportunity for typos, but the first is better practice 
than the second. Gently, please; why?
