(Robb Nebbe responds) 

Offhand I can think of a couple of advantages arising from 
Ada's separation of the concepts of type and module. 

Separation of visibility and inheritance allows a programmer 
to isolate a derived type from the implementation details of its 
parent. To put it another way information hiding becomes a design 
decision instead of a decision that the programming language has 
already made for you. 

Another advantage that came "for free" is the distinction between 
subtyping and implementation inheritance. Since modules and types 
are independent concepts the interaction of the facilities for 
information hiding already present in Ada83 with inheritance provide 
an elegant solution to separating subtyping from implementation 
inheritance. (In my opinion more elegant than providing multiple 
forms of inheritance or two distinct language constructs.) "
