It's because you (...and now me...) are describing a totally new
concept which does not yet exist. Even the "mutable" keyword in C++
doesn't come close to this, because C++ doesn't have either transitive
const or invariant. This really is something new.

(Everyone else, see the "unpaintable..." thread for a first stab at an
explanation).
