Class-Interface compatibility

It is kind of curious why interface typed identifiers don't implicitly
cast to Object, and you must explicitly cast.
But regardless of the reason, adopting a convention (and a bad one at
that) such as prefixing interfaces with "I" probably shouldn't be done
at the language level. And even more, D already has avoided creating
any kind of special types (you can throw Object, for instance, and it's
not a derivative of Exception) so far as I can tell...why start now?
Cheers,
