           Summary: package access can be abused and worked around

/a/m.d:
module a.m;
package void foo() { }

/user/a/workaround.d:
module a.workaround;
import a.m;
auto foo()
{
    return a.m.foo();  // free access!
}

/user/main.d:
module main;
import a.workaround;
void main()
{
    foo();
}

$ rdmd user/main.d

No compile errors!

Even though user/a/workaround is *not* part of the library defined in the 'a'
folder, it has free access to all package 'a' modules.

Package should probably be checked on a folder level and not just on a module
declaration level to make it useful.

 Package should probably be checked on a folder level and not just on a module
 declaration level to make it useful.

Although if a library writer has e.g. 'foo/bar' package split around multiple
directories and is using import switches, then this would break his code.

So this could end up being a stale-mate, unless we re-design access modifiers
altogether (a DIP was already called for by Walter).

Isn't a dup of http://d.puremagic.com/issues/show_bug.cgi?id=143 ?

No, that's related to package not working on variables. It works on functions,
but as the sample shows it can be easily worked around.
