So.. private means nothing in structs?


If I change the struct to a class I get

D:\D\src\build\temp>dmd bug3.d bug3m.d
bug3m.d(6): class A member b is not accessible
bug3m.d(8): class A member foo is not accessible

which is much better.


If I also move the class definition into the same file as main I get:

D:\D\src\build\temp>dmd bug3m.d
D:\d\dmd\bin\..\..\dm\bin\link.exe bug3m,,,user32+kernel32/noi;

D:\D\src\build\temp>bug3m

Error: Access Violation

So.. when the class is in the same module private does not block access 
but causes an access violation instead.

OTOH, that *does* block access to it (at runtime anyhow) ;-) -- Derek Melbourne, Australia

Behaviour is unchanged as of v0.94 - bad/bug.
 If I change the struct to a class I get

 D:\D\src\build\temp>dmd bug3.d bug3m.d
 bug3m.d(6): class A member b is not accessible
 bug3m.d(8): class A member foo is not accessible

 which is much better.

Behaviour is unchanged as of v0.94 - good/expected.
