Oops, I didn't know that. That explains why I didn't see assigning to
this mentioned in the docs. I got the assigning idea from gtkd, they use
this as well. One thing is strange though: If you look at the test case,
in the end:
-------------------------------------
Test test1 = new Test(&a);
Test test2 = new Test(&a);
	
assert(test1 is test2); /* ok */
-------------------------------------
This works, test1 and test2 reference the same object, which means "this
= lookupTable[ptr];" does not only change the local reference when "this
(void* ptr)" is invoked directly. If this is a local reference only,
that shouldn't work at all, correct?
