 ===== Caveats =====
-An exception where it may be helpful not to adhere to the principle are certain algorithms. When implementing for instance a sorting algorithm, keeping the algorithm together can be considered more readable than splitting it up into several small functions. This is because certain algorithms are well known and splitting them up may disguise them. A suitable compromise has to be found in such a case.
+See section [[#contrary principles]].
-See section [[#contrary principles]] for further aspects.

 Now there are two smaller methods each of which is written in terms of a single level of abstraction. This is better readable as no mental grouping is necessary. Furthermore the two methods are still separately understandable ([[Principle of Separate Understandability|PSU]]) so no mental inlining is necessary and if you don't care about the details of the ''toDto'' method, you can just read and understand ''buildResult'' without being distracted by unnecessary detail.
