+1.  Python offers too many convenient ways to do it "wrong".  Zipped
eggs break deployments.  They don't make developers write code that
works in that environment.  Such code only gets written when developers
choose to care about such cases.  If you want Python to excel in these
areas, you need to convince developers to care.
