Dang, I knew I'd choose at least one wrong word in all of that. :-P

What is it's value, then? ... and what is the value of the other  
example I gave?

(What would GHCi print? What is another, perhaps even simpler,  
expression it is equal to? ... a substantive answer please! Then  
please square that with your comment that we don't care how much of  
the list gets evaluated.)

(Jules, thanks for your response. My questions are Socratic, not  
rhetorical. I'm benefiting by having to choose my words very, very  
carefully. :-)
