Jesus, my research project once depended on this file. The day we deleted it from the repository was a very happy one.

That was a fun search and replace exercise I bet... ;-)

I imagine searching for Z, R and O in a large code repository.

Oo, where'd you get the C minimizer?

This is the way that APL programmers write C.
