           Product: D
           Version: 1.010
          Platform: PC
        OS/Version: Windows
            Status: NEW

         Component: DMD

the following module should not compile, but it does. Tested with dmd 0.175, 1.010 and 1.010b.



template Mix(int a) {
        alias typeof(*this) ThisType;
        static assert (ThisType.init.tupleof.length == a);
}


struct Foo {
        mixin Mix!(0);
        int foo;
        mixin Mix!(1);
        int bar;
        mixin Mix!(2);
}

Perhaps D is designed to work this way? Mixin template instances also don't see fields declared after their mixing-in point, so it's kind of consistent... But pretty weird/confusing anyway.
