> Yes, but the code for creating a dict can be simpler. In any case we will better see what format is better when try to write a code.

Note that many annotations are not accessed. RAM usage of annotation information is important than how easy to create dict.

I don't like `(('x', 'int'), ('z', 'float'), ('return', 'Hoge'))` because it creates 4 tuples. It means use more memory, load pyc slower.

Please use ('x', 'int', 'z', 'float', 'return', 'Hoge') instead.
