Standard work with partially long code examples

Clean Code is a key issue in the software development and the corresponding book by Robert C. Martin is a classic you read as a software developer, worked through and should have understood me. Nevertheless, it also says here: judge for themselves whether the technique described in each particular case is reasonable or not. For my taste, the book also contains many places too much source code, in which not even the relevant points are somehow highlighted. This unnecessarily difficult both readability and understanding. Nevertheless, a highly recommended book for all software developers.
