Wire without cascading import

[ssheng]

First of all. Thanks for creating and maintaining this great library. I have a question regarding wire.

It seems like wire does a pkgutil.walk_packages and import all modules through importlib.import_module. This prevents the ability to lazily import dependencies as they are needed especially when there are large libs like numpy and grpcio involved. What is the recommendation to wire without cascading imports?

Thanks,
Sean
