There are actually too parts...

   (% ...)  Handles implicit concatination and string conversion.

And {expr format} handles the formatting, inside (% ...) context only.

So these only work in string format expressions, just like special syntax 
for comprehensions only works in comprehensions.

As I suggested, I think it's the closest you can get and still not put the 
expressions into the strings.

Comma's could be used to separate things, but it's not that much of a 
stretch to go from ....

      'a' 'b'   --> 'ab'

to
      a = 'a'
      b = 'b'
      (% a b)  --> 'ab'

But we could have...

      (% a, b)  If that seems more pythonic.

Cheers,
