I have a very strange effect, I'm not sure what it is about:

Value: {}

WordV: Value {
     Value* get() {}
}

BaseOperator: Value : {
}


Now comes the code using this:

auto op = cast(BaseOperator)(Word.get());
if (op !is null) {...


If get() returns "Value*" it segfaults, if I change it to "Value" it
works. How can this be?

I want to check of the Value returned from get() is a BaseOperator or not.

If this is valid D, I'm not sure what it means :)
