He doesn’t say it is a silver bullet, but Jeffrey Palermo has blogged that limiting code comments increases maintainability. This is definitely something I’ve tried to impress on my current team members. I would only like to add one point, and that is that the approach doesn’t automatically mean your variable names stay relevant.
Maintenance developers will still be able to change the semantic meaning of the variables. Do you really think they’re going to bother changing the name of the variable?
