I'm not sure, but I suspect that closures would be hard to understand
unless one had a good understanding of variable binding, scope, etc.

Are you sure?  I honestly don't know, I'm just asking.  I'm wondering  
if it was hard *because* we are experienced programmers.  Newcomers  
don't have that existing knowledge to overcome.

For example, iterators were quite a bit of adjustment for me when I  
was new to Ruby.  I think the main barrier for me though was mapping  
all my old loop knowledge to the new way of doing things.
