[Python-Dev] String concatenation

[Stavros Korokithakis]

Hmm, thanks, although I don't see why it was rejected, since it seems to 
me that by using the addition operator or triple-quoting all the use 
cases would become clearer and not significantly harder to write, while 
the (often silent) errors would not happen any more.

The PEP only mentions that "the feature to be removed isn't all that 
harmful, and there are some use cases that would become harder", but I'm 
not sure that the "harder use cases" (which ones?) justify the error 
potential.
