I think, instead, the stream API should grow a "print" method (or
whatever it ends up getting called). The example would then look
like:
 sys.stderr.print("foo", "bar", "baz", " ")
It would probably be nice to provide a FileMixin object too. 
(Actually, this would be nice now, so that if I implement read(), I
don't have to implement readline(), readlines(), etc.) The FileMixin
object would make it easy for user-defined file-like objects to also
support the print() method:
 class FileMixin(object):
 """Adds the file methods.
 
 Requires:
 read()
 write()
 
 Adds:
 __iter__()
 next()
 readline()
 readlines()
 writelines()
 print() # or whatever it gets called
 """

You can wordify anything if you just verb it.
