Now to figure out how the frig to implement this at $work.
We haven't used this for the purpose of writing epitaphs, but we could. In fact, since such changes need to go through code review, someone could theoretically author their own removal and add an epitaph of their choice in the commit message; after they leave, the change can be approved and merged in their absence.
Of _course_ the right place to do this is hidden in the compiler.
