<p>As a general rule, pragmas start with lowercase letters while modules start with uppercase letters. The two are different, as well-explained in previous replies. But looking at the first letter usually tells you which you're dealing with. After a while, you'll get used to the convention. Perl doesn't <em>enforce</em> this, but it's standard, common, and good practice.</p>
