(As a nuby,) I didn't know this was possible. Is this ruby way? I presume
this is super ruby way then :-)

I've modified it to the _nuby_ way, like this (just to see if I'm thinking
it right):

	proc 
           do 
                $SAFE = level; 
                yield 
	     end
      .call

And it works still! Very consistent. No surprises for ruby but big happy
surprises for us (nubies ;-)

I think I better read again on procs and calls :-)
