Before I forget, I noticed that the canonical type hasher gets given a bespoke hash code by the type creator. I think the aim is to avoid a generic hasher. This leads to various interesting ways the hash is generated. The attribute variant creator contains a generic hasher anyway. I have patches on the c++-modules branch to canonicalize this hashing.
