alias Spectator::Mocks::Registry::Key
Overview
Entry keys consist of two elements - the type ID and it's location in memory. For value-types, it's byte-representation is is stored in a pool and that location is used.
WARNING The Class#crystal_type_id method, which is undocumented, is used to retrieve the first part of the key.
NOTE Ideally, the type would be used as the first element of the tuple.
Object.class cannot be used due to https://github.com/crystal-lang/crystal/issues/9667
