As an exercise of style, I asked myself: How could I remove
all dependencies on concrete types from the following
algorithm and express it using solely interfaces?

Entertaining.

My rule of thumb is that I feel very compfortable depending on a concrete class that is not going to change. String, for example, is not going to change very often; so I don't mind using it. On the other hand, the classes that I am in the midst of designing and building are changing all the time. So I often build interfaces for those classes to protect me from those changes.
