r1343 introduces a trace procedure. Use it in a similar fashion to print. 
It will wait for all of its arguments to be marked closed, and then send 
them through the logging mechanism so that the end up both on the stdout 
of the executing process and also in the log file.

For example:

  (string r) p() { r="foo"; }
  string s;
  trace(s);
  s=p();
