Maintain a style consistent with the legacy code I am modifying. If they used CamelCasedCaps, so should I, even though my first thought is "ugh, %s/CamelCasedCaps/camel_case_caps/g". As I learn the code base, I get expect certains patterns to appear in certain modules, because I recognize the original authors (now long gone). Failing to adhere to the historical coding precident is a certain way to Warnings and Madness. (Now, when I re-write this sucker.....)
