I would support a proposal to remove the implicit concatenation entirely.

I suspect it would be shot down for backwards compatibility (even in
Py3K), but from a readability standpoint ...

I have never seen a string concatentation that would look worse
because of a "+".

I *have* seen some bugs where a comma was forgotten, and two arguments
got invisibly jammed together.  That's a pain to debug in C; in python
with default values, the interpreter may not even gripe sensibly.
