/* This struct is designed to store data from using directives. It

- of the list. If the imported namespace has been aliased, ALIAS is set to a
+ 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.
- Eg:
- namespace C = A::B;
- ALIAS = "C"

+ DECLARATION is the name of the imported declaration, if this import
+ statement represents one. Otherwise DECLARATION is NULL and this

+ C++: using namespace A;

+ import_src = "A"
+ import_dest = local scope of the import statement even such as ""

+ declaration = "x"

+ The declaration will get imported as import_dest::x.
+
+ C++ has no way to import all names except those listed ones.
