Nice! Thanks,

The big issue is things like this:

   DOUT << foo.getName() << "\n";

When -debug is disable and even when assertions are turned off,  
foo.getName() is still called.  When you use:

DEBUG(errs() << foo.getName() << "\n");

When assertions are turned off, the call doesn't exist.  It is also a  
lot less "magic".
