There was a recent discussion about this (under "implicit string

It's part of the language reference, not an accidental artifact:
http://docs.python.org/2/reference/lexical_analysis.html#string-literal-concatenation
When I say "specification", I mean "specified in the formal notation"
(BNF, etc).
There is quite a bit of Python's lexical analysis that is specified in places
other than the formal notation. That does not mean it is undefined. It is well
defined in the lexer code and the documentation. You suggest that a "rule
probably should be added to the lexer to make this explicit." That is not
necessary. The rule is already there.
