The only thing I captured from re-reading all that was that something like 
`(let' behaves like a function (special form).  The variable setting sets the 
value but do not define any output.

But I also found that by default, a function in lisp returns the value of the 
last expression evaluated as the return value.  Hence, the last expression in 
the body of the `let' clause is the entity that is returned by `let'.
