[issue40080] Stripping annotations out as a new optimization mode

Raymond Hettinger added the comment: Duplicate of https://bugs.python.org/issue3646 This was rejected because it breaks functools.singledispatch(), typing.NamedTuple(), and dataclasses.dataclass(). Also the space savings was negligible -- typically take much less space than for docstrings

[issue40080] Stripping annotations out as a new optimization mode

Pablo Galindo Salgado added the comment: I am -1 to this feature because compared with other optimization levels this can have unknown effects on the runtime, especially on dependencies you do not control. dataclasses is an example, but much more exist. To support this feature we would need

Batuhan Taskaya added the comment: > Note that dataclasses will break without annotations. Yes, that is also affecting this simple tester script. There is no alternative to value-less annotated assignment. I don't think this is preferable but just for information, these are the results for

[issue40080] Stripping annotations out as a new optimization mode

New submission from Batuhan Taskaya : Just like docstrings, annotations do nothing at runtime for the majority of the time. We can just strip out them and gain as much as the docstring optimization in bytecode size on a fully annotated repo. For comparing these two optimizations, I
