Ok, QI is declared like this:
void QueryInterface(in nsIIDRef uuid,
[iid_is(uuid),retval] out nsQIResult result);
Is it true that XPConnect uses the `iid_is(uuid)' so that it knows
what kind of object is coming back? Are dynamically-typed runtimes
the (only) reason for this?
Suppose you wanted to have a:
void QuerySomething (out nsQIResult result);
where that method picked from, say, a static list of iids in an array.
(For the sake of argument, say that there was contract such that the
returned value would never be used to call a method until that value
was returned to a place where the interface was once again possible to
know by other means.)
This is impossible, right?
