So my guess of the solution is this:
Let wingdb_import_hook report "__builtin__" as its module and
'__import__' as
its name, and you are fine.
You're right. The problem with simply using a name other than
__builtin__.__import__ is that it may not be there when a pickle is
loaded because the debugger may not be running. This is illustrated by
the attached failimp.py file. Try running:
failimp.py debug dump
failimp.py load
This simulates creating a pickle when the debugger is running and then
trying to load it when the debugger is not running. The workaround is
to set __module__ to '__builtin__' and __name__ to '__import__' on the
import_hook function.
Thanks,
