deprecated int x;

void main() {
    x = 53;
    int y = x;
}

----------

The bug also shows if x is a member of a struct, class or union, but only if accessing from within it through the implicit this pointer:

----------
import std.stdio;

class ClassWithDeps {
    deprecated int value;
    deprecated static int staticValue;

    void test(ClassWithDeps obj) {
        value = 666;
        staticValue = 101;
        writefln(value);
        writefln(staticValue);
    }
}

Comment 1 Stewart Gordon 2007-12-06 14:53:55 UTC 
For cases in which the member variable is accessed through an explicit object reference, bug 547 bites instead.  When 547 is fixed, this one may affect these instances as well, so fixing that bug may be necessary to confirm that this one is fixed properly.  Hence the dependency.
Comment 2 Walter Bright 2008-06-29 19:10:00 UTC 
I marked this as trivial because it is cosmetic only.
Comment 3 yebblies 2011-06-30 08:17:47 UTC 
This patch fixes all the test cases in this report.
