That limits the number of valid delimiters to a relatively small set.  You
couldn't use any valid operator:

   x = r*a*b

Is that a one character raw string appended to a string called "b", or is
that to multiplications?

sed can do that because its commands are one character long.  Whatever
follows an "s" must a delimiter because it can't be anything else.
