I'm talking about programs that can't be improved no matter what. They do exactly what they're supposed to and will never be changed.

It'll probably have to be something small, like cd or pwd, but does such a program exist?

The answer remains, this tool is not flawed, it's just not the one you want.

Vim could be feature-complete and formally verified and I'm still using Xed.
