[Python-ideas] ImportError raised for a circular import

[Barry Scott]

Recently I fell into the trap of creating a circular import and yet again it took time to figure out what was wrong.

I'm wondering why the python import code does not detect this error and raise an exception.

I took a look at the code and got as far as figuring out that I would need to add the detection to the
python 3 import code. Unless I missed something I cannot get the detection without
modifying the core code as I could see no way to hook the process cleanly.

Is it reasonable idea to add this detection to python?

I am willing to work on a patch.
