Well then I should be grateful for whatever parsing zsh does--at least 
it picks up clear errors in syntax.  But as Bart says, semantics is not 
the same thing.  One can think one understands these things but still 
have a brain full of deep errors.  If I'd been involved in this 20 years 
ago I'd have written: "The Tao of shells--why everything a C coder 
thinks he knows about programming ain't necessarily so."
