      I'm afraid I don't like this. For options you need an operator like ^=
      to be able to prepend something to an option value with ":set". For
      assignments it's very easy to do:

      :let a = '1234' . a

      I think this is used infrequent, at least not often enough to justify
      adding another operator. It's not obvious what it does either, since

      let a ^= x

      would logically mean:

      let a = a ^ x
