--- Comment #5 from FeepingCreature <default_357-line at yahoo.de> ---
No this is a genuine bug. See

"For class objects, identity is defined as the object references are for the
same object."

I ia and ib are interface references, but they are the same object.

D must transform the interfaces into their class reference before comparing,
even if the type is the same; else, multiple implementation of the same
interface must be either merged or made illegal.
