It's what we all want. As written, that's not what it states. This isn't ready to go in until this bug is corrected.

Since the speclet states nothing about changing the way strings are lexed, normal escape character processing should be in effect, and that dictates that \\ is processed into \ independently of what follows. --lars ___ Es4-discuss mailing list Es4-discuss@mozilla.org https://mail.mozilla.org/listinfo/es4-discuss

This states that: "abc\\ tde" evaluates to the string "abcde". Is this really what we want? I'd find such nested escape sequences really strange.

This (and the line terminator normalization draft) seem to be in
restricted parts of the wiki. Could they go somewhere public?

ES4 draft last call: line continuation in string and regex literals
Last call for the line continuation spec:
http://wiki.ecmascript.org/doku.php?id=spec:line_continuation_in_strings
("Last call" = it will be taken into the language spec within a week or
so unless there's opposition now.)
