I haven't actually checked or anything rash like that, but I'd imagine
the answer is something like:
The two strings are separate statements as far as the parser is
concerned, and the "concatenating adjacent strings" thing only
happens within an expression.
You can do this:
>>> "con"\
... "cat"
'concat'
