Is #r"..." convenient enough?

If I have a string with lots of double quotes, I still have to escape
every duoble quote.

Maybe better to change to #r"..."r#, or even #r<<<<"...">>>>r# (user can
insert any number of < and > but they must be paired to avoid the
escape.)

I'm with raw string reader syntax because I often want my program be
self-documenting, so I write a lot in docstring.

BTW, Naoya, have you test raw string syntax in propertized string?
e.g. #(#r"foo bar" ....)
