Typing module gone missing

Anvil Q&A
8

We’ve had a look and this is the result of a skulpt update where function annotations that were previously ignored, now do something on the client.

try:
    from typing import Any, Dict
except:
    pass

def foo(x: Dict[Any]) -> None:
    pass

# Dict is not defined
# previously no error because the annotation was ignored by the compiler

The suggested fix related to this post with the following adjustments:

try:
    from typing import Any, Dict # works on the server
except ImportError:
    from .fake_typing import Any, Dict # works on the client side

# fake_typing module
class GenericAlias:
   def __getitem__(self, key):
        return self

Any = GenericAlias()
Dict = GenericAlias()

What happens to the annotations now? 
def foo(x:str) -> None:
    pass

print(foo.__annotations__)
# {'x': str, 'return': None}
