[issue3436] csv.DictReader inconsistency

[Raymond Hettinger]

Raymond Hettinger <rhettinger at users.sourceforge.net> added the comment:

I think this is the wrong approach.  It would be better to have a 
separate getheader() method.  Having __init__ do the deed is at odds 
with other uses of __init__ that only do setup but don't start reading.
