But what about this, what would the bytecode will look like in this case (where
the annotations don't exactly follow each other?)
a: int
T = TypeVar('T')
b: T
b1: Gen[T]
X = TypeVar('X')
c: X
d: str
Do you propose to build 2/3 different dicts and apply them one by one to allow
calls to access that frame and recover the annotations?

What kind of optimization do you target? It would be really cool if you could
get us some numbers with a draft patch (like comparing to test the import time
of a module heavy with annotations, or even maybe some real-world examples.
Here is a list of heavily-typed projects:

Would love to see an import time comparison, or something similiar.
