Hi
As I understand it, regular expressions will be added to the next standard.
However, I don't see a proposal for a raw string format, like r""-strings in
Python. Clearly that would be very nice to have since regular expressions
do contain an awful lot of backslashes. Have I missed it or is it waiting
for
N1429 to finish, or what?
(Raw strings are simple c-strings that can contain special characters which
gets translated by the compiler.)

You have them in C# too, there they are prefixed by @ |
This makes it possible to write e.g. @"This is a CR/LF rn"
Fact is that specially when doing regular expressions I seriously miss
a "raw string" specification like you have e.g. in C# since regualr
expressions do LOTS of ""'s.
But there are backdrafts too, firstly it's a language enhancement.
0x standard officials says that they will try to not suggest so many
new language enhancements but rather build up the libraries.
This is probably because it's much easier to get compiler writers to
implement libraries as opposed to changing the language semantics.
Another issue is e.g.
#define @ myX
string g = @"HellorntEarth!!";
??
List goes on...
