Yes. The only ambiguity I can think of would be tuple literals.

My first thought was to add separator and newline attributes to file objects
and keep print just like it is, but the print object is more flexible. You
could easily add further extensions, e. g.
I'm not sure what to do with different printers operating on the same file -
most likely sys.stdout. Should they share (some) state like today's
softspace, should they operate as if they were the only one or should
multiple printers be disallowed?
Another thing that is not addressed is how to suppress newline. I can think
1 a method: print.write(1, 2)
2 a keyword argument print(1, 2, newline=False)
3 a special marker object: print(1, 2, suppress_newline)
4 make no newline the default
I tend to option 1 but don't particularly like it either.
PS: Actually, when I started to write I thought I knew how it should be
