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.

Oh. I just realized this happens a lot out here. Where I work, we use scons, and each SConscript has a long list of filenames:

sourceFiles = [ 'foo.c', 'bar.c', #...many lines omitted... 'q1000x.c']

It's a common mistake to leave off a comma, and then scons complains that it can't find 'foo.cbar.c'. This is pretty bewildering behavior even if you are a Python programmer, and not everyone here is.
