+- Refactor name-analysis to add custom errors for name-analysis only, which can then be tested.
+- Refactor `pub` fields of AST structs into private fields accessed by methods.
+
 ## General Pipeline

 - Transform a single file into a `CompilationUnit` AST node.
 - Gather all `CompilationUnit`s and determine which modules need to be built.
   - A module corresponds to one syntactical namespace `ns`, but not its children!

   appropriate objects, such as `DmInterface`, `DmImplementation`, `DmFunction`, or `DmConstant`.
 - Thus, a `DmModule` is a single-file containing all the code for one namespace, but not its child namespaces. Using
   the above examples, the following DmModules would be created, with their appropriate contents:
-    - `pub ns std`: *no contents, only metadata.*
-    - `pub ns std::core`:
-      - `pub fn std::core::foo`
-    - `ns std::core::bar`

-      - `prv fn std::core::bar::hello`: only accessible inside `std::core::bar`.

 ## More Namespace Rules
 
 Top-level namespace declaration:
+
 ```
 decl pub ns std
 ```
 
 Nested namespace declaration and members:
+
 ```
 ns std::core // indicates that all members of this file are in the std::core namespace
