says that names from namespace IMPORT_SRC should be visible within

namespace IMPORT_DEST. These form a linked list; NEXT is the next
|
|
element of the list. If the imported namespace or declaration has
|
|
been aliased within the IMPORT_DEST namespace, ALIAS is set to a
|
|
string representing the alias. Otherwise, ALIAS is NULL.
|
|
DECLARATION is the name of the imported declaration, if this import
|
|
statement represents one. Otherwise DECLARATION is NULL and this
|
|
import statement represents a namespace.

All the entries of A get imported except of "x". "x" gets imported as

Fortran has no way to address non-local namespace/module.

C++ cannot express it, it would be something like: using localname
