The only change was that the new escape sequence for skipping spaces now is written '\z'. There is no new rule "\punctuation always means puntuaction". This is only a kind of guideline for choosing escapes. Undefined escape sequences are still undefined and should be avoided.
Sorry, I misunderstood the line, it was clarified by Gé's excerpt of diff. I wasn't aware of the previous \* meaning.
So, if I understand correctly the manual (I should have started to read it...):"The escape sequence '\z' skips the following span of white-space characters, including line breaks; it is particularly useful to break and indent a long string into multiple lines without adding the newlines and spaces into the string contents."
x = "Foo\
Bar"
is now the same than
x = "Foo\z
Bar"
and the same than
x = [[
Foo
Bar]]
right?
(But maybe I did not understand your message. What do you mean by "non consistent behavior", when compared to how it was and to how many other languages handle escape sequences?)
Well, I jumped on the "'\punctuation' always means 'punctuation'" sentence, which I don't understand, then...
Mmm, if it just means the behavior is the same than C's one, I see my reaction is stupid. Sorry for the noise. -- Philippe Lhoste -- (near) Paris -- France -- http://Phi.Lho.free.fr -- -- -- -- -- -- -- -- -- -- -- -- -- --
