Well that is not sure. I don't have the answer.

BUT !

In D, you'll find many places where identity and value are 
conflated. This is one instance of the problem. This is pretty 
bad in general.

implicit cast to bool usually imply using the value (otherwise, 
an int would always cast to true) and it is rather surprising 
that it does check for identity for slices.
