Yeah, thats cool.

While were on the subject, what is technically the difference between some 
block, such as { |n| 1+n }, and the corresponding lambda { |n| 1+n }, or 
more specifically, how does the interpreter treat them differently?  Also, 
could I assign a lambda to a variable as I would in scheme to create a 
function?
