Currently inspect.stack() returns a list of 6-tuples.  I suggest to make it return a list of named tuples, so code that only needs one tuple element can get it by name.

Current behaviour:
% ./python -c 'import inspect; print(inspect.stack()[0])' 
(<frame object at 0x157fb38>, '<string>', 1, '<module>', None, None)

Suggested behaviour:
% ./python -c 'import inspect; print(inspect.stack()[0])'    
FrameInfo(frame=<frame object at 0xddab38>, filename='<string>', lineno=1, function='<module>', code_context=None, index=None)
