An implementation issue: that generator expression will get expanded into a
tuple, so you shouldn't use that for outputting large sequences.
I don't much care for 'output' as the name, or 'end' as the end-of-line
arguments, but for the most part I like the semantics; being able to drop
the separator or change the end-of-line string make lots of use cases
straightforward, and perhaps almost worth the parentheses.
My inclination would be to call the function 'print', though, and rename
'end' to 'trailer'.
