  * milestone:  => After 2.0

Comment:

 You are right of course, string concatenation should work everywhere, but
 right now it only works for header assignment.

 To properly fix this, requires major surgery to the VCL compiler, which I
 don't want to do right before the 2.0 release.

 The obvious workaround is to use header assignmnt as a temporary variable:
 {{{
      set req.http.foobar = req.url "#" req.http.host "#";
      purge_hash(req.http.foobar);
      remove req.http.foobar;
 }}}
