+<p>
+ Normally functions from other modules are used in a qualified fashion, with
+ the module qualifier before function name. For example,
+ <code>io.println("Hello!")</code>.
+</p>
+<p>
+ It is also possible to specify a list of functions to import from a module in
+ an unqualified fashion, such as the <code>println</code> function in the code
+ editor. Because it has been imported like this it can be referred to as just
+ <code>println</code>.
+</p>
+<p>
+ Generally it is best to use qualified imports, as this makes it clear where
+ the function is defined, making the code easier to read.
