There was a problem hiding this comment.
Explicitly annotate the variables as bytes, since right now the inferred type will be bytearray, which doesn't have a mypyc primitive type, so it reverts back to object.
Also test calling a function that accepts bytes with an actual argument that is a bytearray object annotated with type Any, to check the runtime type checking from Any to bytes works if the runtime value is a bytearray .

bytearrayis treated as a subtype of bytes by mypy, even though they behavior differently in some cases. We keep this design and check bytearray before calling corresponding cpython API.Test Plan
Adds tests for
bytearraycreation.
