Re: Default value for global-ignores - Import excluded .so files

The main issue I have is that the user expects import to import everything.
Anyone reading the documentation on import wouldn't guess that import
doesn't import everything. It just isn't safe to assume that the user
doesn't want to import a .so or .pyc file or anything else. I agree that
you generally wouldn't want to do such things, but importing the jdk is a
case in point. Wouldn't it be safer to just let people add their own
extensions to the global-ignores variable and default to nothing?
