I think the need of classes comes when you need objects thus a set of 
variables with an identity and that may be created N times. Classes are 
object factories.

A second aspect is inheritance: classes may inherit from other classes 
and reuse existing functionality and data structures for their objects.

In cases where you only need to encapsulate a single set of data and 
functions modules are the best choice.
