no-implicit-reexport resolves implicit re-exports as Any

[DetachHead]

# foo.py
class Foo:
    ...

# bar.py
from foo import Foo

# baz.py
from bar import Foo # Module "bar" does not explicitly export attribute "Foo"; implicit reexport disabled  [attr-defined]

reveal_type(Foo) # Revealed type is "Any"

mypy should still resolve the import like it does when no-implicit-reexport is disabled.

in my case, i'm trying to use a library that imports its own classes using implicit re-exports, which results in pretty much everything being treated as Any in my project

As a workaround you could apply an override to the mypy config:

[[tool.mypy.overrides]]
module = "thepackage.*"
implicit_reexport = true

Just to be clear - are you expecting mypy to give the error (... does not explicitly export attribute ...) but then still treat it as being exported?

Also, in your examples the files are all .py files - are there stubs for the external libraries? If so, can you change the stubs to have explicit re-exports?

yes

the library i'm using has types defined in its .py files, but i'm pretty sure it would behave the same if they were stubs. i also can't really fix them without making stubs for the entire thing which would be a waste of time because they're already typed

using __all__ = ["Foo"] mypy will know about it.
