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.
