[Web-SIG] about Py[Type]_Check in a WSGI implementation

[Manlio Perillo]

The WSGI spec requires the response headers and sequence items to be, 
respectively, List of Tuples and Strings.

However only for the response headers it explicitly requires them to be 
a Python List, i.e type(response_headers) is ListType.

What about the other objects?

In the current implementation of WSGI for Nginx I always use 
Py[Type]_Check, and not Py[Type]_CheckExact.



Thanks and regards   Manlio Perillo
