Example

I discovered something odd when I put a struct into an unittest.

If you place a struct inside an unittest with a mixin template the compiler
adds an extract (void*) element to the struct.

carsten at spaceship:/tmp> dmd unittest_odd_void_ptr.d -unittest
(int, string)
(int, string, void*)
(int, string)
carsten at spaceship:/tmp> ldc2 unittest_odd_void_ptr.d -unittest
(int, string)
(int, string, void*)
(int, string)

See the attached code.

It is not a practical problem. I just found it a little odd and properly there
is an explanation.

Keep up the good work.
Best Regards
Carsten
