I get tripped up by cyclic imports once in a while, but I think once you understand how imports work in general, it's really no big deal to work with/around their quirks. Every language has these kinds of quirks--I'm pretty sure it's unavoidable. I found this article helpful for coming to terms with how imports work in Python: http://effbot.org/zone/import-confusion.htm -wlb --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "pylons-discuss" group.
