Hydroper commented on issue #100: Literal string to identify package public namespace URL: https://github.com/apache/royale-compiler/issues/100#issuecomment-560565835 The purpose would be to improve readability in large programs. In C# or Rust you have these directives: ```rust use foo::lib::utils as qux; ``` ```C# import Qux = Foo.Lib.Utils; ``` In ActionScript, because there is not something like `import qux = foo.library.utils.*`, programs where scope has lexical conflicting names (like `package1.Item` and `package2.Item`) the programmer must use the fully package-qualified names. For certain compiler writting methods, it is good, for instance, to know what belongs to semantic data model and what belongs to bytecode structure. (In my mind, I reflect names such as `sem::Activation`, `bc_ns::MetaData`). > The code that determines if two namespaces are equal requires that the "kind" of both namespaces is also equal. So, a namespace defined in ActionScript code (`ABCConstants.CONSTANT_Namespace`) can never be equal to a package namespace (`ABCConstants.CONSTANT_PackageNs`). For most cases, when namespaces are represented as heap objects, pooling explicit namespaces (except these of anonymous identity such as `namespace ns`) and comparing by reference should work.
