Yes.  The meaning of that would certainly need to stay the same.

However, the following is currently invalid, but would mean what is desired 
if consecutive string literals were merged by the parser, as in C:

  a <- ("foo"

In practice, most uses will be of something like

  cat ("I'd like to teach "
       "the world to sing"

which unambigously means the right thing without further effort.

So just doing like in C seems the way to go to me.
