Did you consider a variation that eliminates the start_response but
returns status and headers as first item of the iterable? Considering
how response is usually generated it could save some code in some
cases and wouldn't add any overhead in others, it also has a pleasant
similarity to the HTTP response format:
def simple_app(environ):
"""Simplest possible application object"""
status = '200 OK'
response_headers = [('Content-type','text/plain')]
yield status, response_headers
yield 'Hello world!\n'
Anyway, whichever way will be accepted they are easy to adapt to one
another with a decorator.
