Summary: interpret string argument as filename

Initial Comment:

I think it would be great if, in general, anywhere
a python function asks for a file object, supplying
a string would be interpreted as a filename.

For example, one can do:
cPickle.dump('mypicklefile', myobject)

instead of:
f=file('mypicklefile','w')
cPickle.dump(f,myobject)
f.close()

Much faster in an interactive session!  And very
easy to implement.  And similarly for cPickle.load()
and lots of other functions.  Pickling of multiple
objects could still be accomplished through the
long form above.

Thanks,
-Russ

I prefer leaving the functions as they are now because:

* the current way supports and encourages explicit file 
closing 

* supporting this everywhere would unnecessarily complicate 
the code

* munging parameters unnecessarily confuses/complicates 
the API
