OK.
I think there is more to do though as I suspect if you have type a
contains type b contains type a then you will need to know what types
have already been added.
Probably does that already.
Will see if I can make a sensible test.
Currently, an exception is thrown saying that this is not allowed. So
really it is an enhancement.
Oh. There is a "bug". A typo. "itsself" is in exception rather than "itself".
I'll report this as an enhancement.
