  This allows dumping expressions (Init *) as soon as they become
  concrete.  Both of these take a string as the first operand that
  prefixes the dump of the expression.
  
  `!dump` can be used in a expression/functional context. For example:
  
      !foreach(i, lst, !dump("elt = ", i))
  
  `dump` can be used in a "statement" context:
  
      def c: C<3>;
      dump "c = ", c;
  
  `dump` is implemented as a syntactic sugar. The above dump is parsed
  into:
  
      assert 1, !cast<string>(!dump("c = ", c));
