KillerCodeMonky: The tendency to want to “fix” things is sometimes part of the problem. It’s called lava flow pattern, and it’s when your codebase is programmed in waves of different guiding design and architecture. One of the best things you can do in an old codebase is just follow existing patterns and design, even if you don’t agree with them. If you’re going to refactor anyway, make it very obvious where the line is between old and new, so that others know which design to follow where. Preferably putting the new stuff into a separate namespace or even library.
