The same that a good sentinel value is one that is invalid. A good escape
character is one that is rarely used. If as suggested $() or @() is used, one
would have, unless extra look ahead magic is added to the parser, would have to
write string like "0.99\$" and "swift-evolution\@swift.org"; that's assuming
only \() is changed and not all escaping. Using @ or $ for all escaping is so
ugly to me, that I cannot write an sample of what it would look like.
One could of course argue that the look ahead is tiny, but escaping in the rare
case that "$(" need to be displayed one would have to use "\$("; so some $ need
escaping, whic can be seen as inconsistent and confusing.
So sticking to '\' looks like a good idea.
