The issue, as I recall, is that for Python 3, they are changing print
(without parentheses) to require parentheses. This change alone (and
there are others like this in Python 3) will necessitate a *lot* of code
rewrites. Sometimes I wonder about Guido van Rossum.

I tend to do it the way Tedd does, but I'm rethinking this. I recently
had occasion to do a lot of programming in C and Python, and one thing
stood out at me: I can't recall another language which allows
interpolation of variables within strings (without significant diddling,
if at all). It caused me great difficulty because I'm so used to doing
this in PHP. I can convert from '.' to '+' (as in most languages) in my
mind, but embedding variables in strings was a harder habit to break. My
opinion is that the dot operator used this way was a mistake for
PHP. Not using the dot operator to mean "concatenate" would mean we
could use it to replace the accursed '->' for class/method selection.
And the plus operator is obviously a more natural fit for string
concatenation.
And yes, if you're going to use the dot operator, surround it with
spaces for readability.
