Hello,
This morning I tried to fix an issue for a while before I realized I had a circular import. This issue is not obvious because you get a cryptic error, like an AttributeError and it can tak a while before finding out.
I don't know of this was mentioned before, or how hard it would be. But it would be nice if Python had a specific "CircularImportError" raised in that case, or something.. That would be a fabulous hint for developers.
Cheers Tarek
