It works after I added 'static' to the declaration of

I fiddled around with it for hours before I tried 'static'
there, because I've only been studying D for a week, so only
about half of this code and the error messages made any sense
to me when I started on it.
Once it started passing all the tests, I still didn't quite get
how it all worked, because of suspecting there was a typo in
the code between writing TestClass and testClass. So I tested
whether specific instances are called (instead of maybe just
the first one constructed) by adding a static counter to
TestClass, and storage of the counter by each instance. It
looks all right.
I'm pretty sure this is a bug. I'm going to file a report. If one
of those template works, both should.
I have been trying to build a reflection system over the last few
weeks, and noticed different incarnations of this problem several
times:
<b>
&(__error).instanceMethod
</b>
In certain cases, the compiler seems to drop the enclosing type
of the method, but I'm not sure why.
This error seems like it may be related some how:
enum index = __traits(getVirtualIndex, TestClass.instanceMethod);
enum p = TestClass.classinfo.vtbl[index];
The above code will produce this error:
Error: typeid(main.TestClass).vtbl is not yet implemented at
compile time
but if this is the problem, shouldn't Both of the test cases fail?
