-1. They have their use, but more in controlled situations. If you have "global" env vars that you only want to use with Python 2.x, write a wrapper for Python 3 that invokes it with -E.
Perhaps a case can be made for Python 3 to assume -E by default, with a -e option to enable reading of the environment variables?
That way naive users could run Python3 without tripping over existing Python2 environment variables, while other tools could readily set up a different environment before launching Python3.
Naive users using environment variables? That's a recipe for disaster in any version! :-) -- --Guido van Rossum (python.org/~guido)
