Indeed. And as a matter of fact I can't recall that particular 
statement. Who said it and in what context? The main rule that matters 
to E (for many reasons) is about globally mutable state which is a 
complete no-no. But non-local returns? The only issue I can imagine with 
this is that code could conceivably "escape" from an evaluation which 
may make it harder for auditing but that's about all I can see.
