Similar kind of thing to what's happening here:
>>> print "Hello,", "world!"
Hello, world!
>>> print ("Hello", "world!")
('Hello', 'world!')
And for that matter foo(a, b) v. foo((a, b)). Commas make
tuples, but they're also argument separators, and if you're
using a tuple as an argument you need the brackets to
indicate precedence.
