This allows parameterized types to reference each other with a different set of parameters. This is required for instance for IIterable<T>, that needs to reference IIterator<T>.
The partial specialization is recorded by adding a new parameterized type, referencing the original one as its template. The parameterized type chain will be resolved all at once when the type is declared.

In general, we shouldn't assert or crash on invalid or unsupported syntax. In this particular case, I don't think there is anything special we need to do about those statements, so it seems to me that removing fprintf() and assert() is all we need for those statements. However, I was also able to crash widl by adding a struct declared inside templated interface (which should likely be not supported anyway).
Thanks,
Jacek

Sure, I'll make those error case nicer. I think it's also some remains of development code that I never cleaned, thanks for noticing it.
