Can you help me remember this unix-ish koan?

(not sure if the right subreddit, but here goes)

A while ago, I read something in the same style as Unix Koans, and I'm trying to find it again.

The topic of that particular koan was about macros and code reuse. All I remember is that the neophyte went up to a monk who said some undecipherable string of macros, and the neophyte somehow learned that after a certain point, the more you try to reuse, the more incomprehensible code becomes.

Does anyone remember what I'm talking about or did I dream this up?
