that's obviously not true: environment dictionaries cannot be reused,
environment items cannot be lazily initialized (since you require apps
to use a PyDict), and the code using WSGI variables has to use dict
access syntax (x["y"]) instead of standard attribute access (x.y).

so "def a(b)" is easy to write, but "class a" is hard to write?
you're obviously not interested in feedback from experienced Python
programmers. I'm sorry I wasted everybody's time.
