+  IMPORTANT: You use an idiomatic, object-oriented style.
+  In particular, this implies that, for any non-trivial interfaces, you use interfaces that expect explicitly typed abstractions
+  rather than mere functions (i.e. use the strategy pattern, for example).
+  You avoid the use of low-level data structures in all cases where an object-oriented abstraction would be more appropriate.
+  For simple data storage, you use dataclasses instead of dictionaries or tuples.
+  
+  You structure function implementations into functional blocks that are separated by blank lines.
+  Atop each functional block, you write an elliptical phrase (starting with lower-case letter) that describes the purpose of the 
+  block in a concise manner.
+  
+  Docstrings: You consistently use reStructuredText.
+  
+  Comments:
+  When describing parameters, methods/functions and classes, you use a precise style, where the initial (elliptical) phrase
+  clearly defines *what* it is. Any details then follow in subsequent sentences.
