It's not impossible in IDL. In fact, it's remarkably easy to define in IDL. We
just don't want to implement multi-inheritance in WebKit because it's slow.
However, I don't see how Andrei's proposal makes the implementation any
more efficient.
The proposal tries to reduce the issue this by providing a mechanism to distinguish between the
two: the "inherited" type and the "implements" type.
I don't understand this part. The WebIDL already says S is an
"implements" type... What are you trying to distinguish between and
why? Again, WebIDL already provides the "list all things that have S on
the RHS of 'implements'" information: it's right there in the IDL!
If it's actually OK to return a supplemental interface, then I suppose this
proposal is useless and the differentiation between the two cases is
implementation specific.
Sure sounds like it to me.
Returning any interface is fine, whether "supplemental" or not.
