> Being DRY usually makes decoding easier, not harder
"Usually" being the keyword and what the article is all about IMHO. I work in a codebase so DRY that it takes digging through dozens of files to figure out what one constant string will be composed as. It would have been simpler to simply write it out, ain't nobody going to figure out OCM_CON_PACK + OCM_WK_MAN means at a glance.
