digitalmars.D.learn - with statement doesn't call struct destructor?

     writeln("with:");
     with(S(true)) {

}

Output:

  this
  ~this

Report it on bugzilla. Walter has been fixing issues with destructors for 
temporaries lately. They've been buggy for a while. A fair bit of the problem 
was fixed in dmd 2.053 but not all of it. If you're not using 2.053, then 
that's probably why the code is broken. If you are using 2.053, then Walter 
needs to be aware that that particular use case hasn't been fixed yet.
