[Python-ideas] duck typing for io write methods

[Wolfgang Maier]

Dear all,
currently - and referring to Python 3 - the write methods of the different
io module objects work on bytes and str objects only. The built-in functions
print() and bytes(), on the other hand, use an arbitrary object's __str__
and __bytes__ methods to compute the str and bytes they should work with.
Wouldn't it be more consistent and pythonic if the io write methods behaved
the same way?
Best,
Wolfgang
