My first try to avoid this "circular" bug work with opDispatch. 
(As you can read here on my blog:

Now i had a new idea to save the Reference and call only these, 
it seems that it works fine and with a lot less code.

Just for testing. ;)

@Alex Rønne Petersen:
Thanks a lot, i use assert(obj); that seems to serve the purpose.
I hope in the next version "alias this" is more stable.
