The Law of VIM:
For each member b of the possible behaviour space B of program P, there exists
a finite time t before which at least one user u in the total user space U of
program P will request b becomes a member of the allowed behaviour space B'
(B' <= B).
In other words: Sooner or later everyone wants everything as an option.
