You might be missing the point here ;-)

Of course my background is in C#, where I (regulary) use a 
decimal type. But my knowledge of D is somewhat limited - I don't 
think it even has a decimal type?? - and the code was merely an 
example (as per the name of the module) to demonstrate code that 
desires to narrow the visiblity,in a particular case, not widen 
it (with package). Nothing else in the code is relevant here, 
except 'how' to implement that programmers desire.

In that example code, it is 'scopeprivate' that allowed the 
programmer of that code, to do just that, in an explicit and 
enforceable manner.

Without scopeprivate, I'm not sure how that programmer could have 
expressed that intent 'in a meaningful way', and certainly not in 
a way that is enforceable.
