How does being the "closure" of a concept in the language make it
a "rigid must"?
The point of a programming language is to solve programming problems,
right? In the case of MI, for instance, Ada shows that in fact it is
_not_ a "must"! Composition can be made sufficiently powerful (with
access discriminants) to solve the pogramming problem in this case, so
it's hard to argue that MI is a must-have, other than on purely
theoretical grounds.
