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.
Maybe more specifically, a module could be marked as "loading" in some fashion, until it's been completely executed. Any AttributeError from a loading module would instead raise something like CircularImportError (subclassing AttributeError). -- Ian Bicking | http://blog.ianbicking.org
