Hi Michael,

Here is a strawman syntax for new quoted strings that would only allow

You introduce a new lexical token to Sieve, thus changing the Sieve
syntax.  I don't think the base spec allows that.  Sieve has a very
small syntax, moving most stuff to the semantical layer for being very
extensible, pretty much like LISP does.

The variables extension, for example, introduces the concept of expanding
strings, but only at the semantic level.  Syntactically, strings still
look the same.

How about if 'require string-escape' is present in the script, then ALL strings following that will be of the new 'escaped' form. i.e. a global switch covering all strings used in the script.
