private attribute don't function?

[Adam D. Ruppe]

http://dlang.org/attribute.html

"Private means that only members of the enclosing class can 
access the member, or members and functions in the same module as 
the enclosing class. Private members cannot be overridden. 
Private module members are equivalent to static declarations in C 
programs. "

In D, private is only hidden to different modules. If it is in 
the same module, they can see it anyway.
