Description Asumu Takikawa 2022-11-02 18:51:33 PDT

In the Wasm GC proposal, anyref is the top of the type hierarchy for new GC types. There are two separate hierarchies in addition for extern references and function references.

(it is possible to go between the anyref world and extern world via `extern.internalize` and `extern.externalize`)
