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.
C++: using namespace A;
Fortran: use A
import_src = "A"
import_dest = local scope of the import statement even such as ""
alias = NULL
declaration = NULL
C++: using A::x;
Fortran: use A, only: x
import_src = "A"
import_dest = local scope of the import statement even such as ""
alias = NULL
declaration = "x"
The declaration will get imported as import_dest::x.
C++: namespace LOCALNS = A;
Fortran has no way to address non-local namespace/module.
import_src = "A"
import_dest = local scope of the import statement even such as ""
alias = "LOCALNS"
declaration = NULL
The namespace will get imported as the import_dest::LOCALNS namespace.
C++ cannot express it, it would be something like: using localname = A::x;
Fortran: use A, only localname => x
import_src = "A"
import_dest = local scope of the import statement even such as ""
alias = "localname"
declaration = "x"
The declaration will get imported as localname or `import_dest`localname. */
