About comments, deodorant for bad code, and comment removal by refactorings

Hi folks,

this one jumped right into my eyes: "Comments are not evil by themselves,  
but are sometimes used as a deodorant to cover bad code. Often we can  
remove the comments after doing some refactorings, because they are not  
needed anymore. The code should be self-explaining."

Formal Concept Analysis", see
