Eiffel defines $ as returning a POINTER. So there is now way to
discuss the semantics, you have to define your own. Luckily the
implementation in SmallEiffel makes it easy to extend it.

Interesting. But it more and more tells me that ECMA Eiffel will never
ever get completely implemented (like the latest SQL drafts etc.) and
thats why i say, it is wasted time. Also i'm using '$' explictly to
fool the typesystem, seems that this is not possible anymore.
