- Add `forth-like` mode. This mode should allow defining words similar to forth. It should have a built-in word for `assembly output` that can be implemented by the user.
- Add `.extern` directive allowing the user to define external labels
- Add `.scope` for `.def` and `.de.` variables
+- Add `#cop n, ...` preprocessor directive. It should work just like .rep but just insert the line n times into the source code and then preprocess the result.
