List comprehensions are shiny and new and theoretically sound, and
definitely make things more clearer (sic) in plenty of cases, but
this one seems gratuitous to this old-timer.  What about:

    to.write( separator.join( map( str, args ) ) )

I'm half-tempted to suggest that there be a string.join_as_strings
method (or something with a more concise name) like this:

    class string:
        # other stuff elided to conserve bandwidth
        def join_as_strings( self, list_of_objects ):
            self.join( map( str, list_of_objects ) )

but it's (obviously) easy enough to create as necessary, even as a
(gasp!) stand-alone function:

    def join_as_strings( list_of_objects, separator = ' ' ):
        separator.join( map( str, list_of_objects ) )
