Importing selected functions reduces namespace pollution and memory usage, since aliases do take up space. Of course you could just use the OO interface instead.

Note that your particular example is actually a counter-example, because CGI prints "Content-Type: text/html; charset=ISO-8859-1" in order to prevent cross-site scripting attacks. This demonstrates how the "just code this part yourself because it's too simple to load a module" attitude can lead to half-assed and broken code if you don't fully understand the problem you're trying to solve.
