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.
