Raw string literals -- restarting the discussion

This sounds a lot like what Swift does.

Jim has already noted how using \” as a raw delimiter has the effect of suggesting the escaping is “distributed over the string”, which is a nice trick.

Swift unifies raw and escaped strings in this manner, by parameterizing on the number of #.  Unfortunately, if we try to emulate this exactly, because of choices we’ve already made (for the zero-backslash case), we end up with an asymmetry that the Swift approach lacks.  

Still, this approach is something we are considering as a possible inspiration.

There are some good thoughts in here.  Will toss those into the stew and stir….
