-1.  I use it a fair bit, and prefer it to explicit concatenation.  But 
then I come from C, so I'm used to it.

Is that assertion true?  In all Python compilers?  I would expect the 
constant string implicit concatenation to produce single constants 
efficiently, but explicit concatenation doing the constant folding is a 
much less sure bet.
