Classes are not only for reusing the same syntax but also for polymorphism.  
For example, the Num class doesn't exist solely for the purpose that I can 
use the + operator with different types.  It's also for the purpose that one 
can, for example, define a function which sums up the elements of a list 
where the element type isn't restricted to one specific numeric type.

I'd say, classes in Haskell are similar to interfaces in Java.
