How about a "having_first_done" keyword?

 printf(" world\n") having_first_done printf("Hello");

There are many times when it is useful to specify actions in a different
order than they should be executed, and there are plenty of existing
ways to write C++ where things happen in an order that is different from
the apparent reading order of statements. But I don't think readability
will be improved by something as clearly Yoda-speak as "return if".
