 The design is from two concerns.
 
-1. A programmatic approaches may cause inconsistency at runtime, which is difficult for troubleshooting. For example, if one declares the aliasing in `mod/__init__.py` and uses the new keywords in `mod/A.py`, the aliasing works fine if `mod/A.py` imported as `mod.A`, but fails if run as a standalone script.

 2. The compiler and formatter should behave consistently when processing the same file. If a programmatic approach used, the formatter must apply semantic analysis to figure out the aliasing rules, which is far more complicated.
