So well put.

Too bad it's not just juniors who write code like this. I wish I could show the sample code and the TODO comments to one of the "senior" engineers I work with. Because it's exactly (and I mean, EXACTLY) like a few hundred functions he wrote in our codebase in the past few years.

How do you suggest this sort of change of approach to someone who's your peer instead of a n00b you're training up, without sounding condescending or insulting?
