the previously imported type pointer so that we have exactly one version
(i.e., one pointer) for each named type (and read but discard the current
type encoding). Unnamed types simply encode their respective fields.
Aliases are encoded starting with their name followed by the original
(aliased) object.
Aliases are encoded starting with their name followed by the qualified
identifier denoting the original (aliased) object, which was exported
earlier.
In the encoding, some lists start with the list length. Some lists are
terminated with an end marker (usually for lists where we may not know
